C++ windows programming?

Hi this is in C++ using Borland....i have an error "Constant expression required" on this line : "TableType aTable[x];"...it seem that the number from "edit-%26gt;text" is not valid...Can somebody tell me why it wont take the value of "edit-%26gt;text"?





x=edit-%26gt;Text.ToIntDef(0);





TableType aTable[x];





aTable[x].tableNo= MyRest.findTable(edtNo-%26gt;Text.ToIntDef(0)...


aTable[x].computerType = (edtname-%26gt;Text.ToIntDef(0));


aTable[x].name = GuestName-%26gt;Text;


aTable[x].arrivalTime = Arrival-%26gt;Text;


aTable[x].departTime = Departure-%26gt;Text;

C++ windows programming?
the compiler needs to know the size of the aTable array so it can allocate the memory for it. If you give it fixed size it will work, something like:


TableType aTable[50];


Another option is to malloc().

How to install Borland Compiler?

I recently downloaded the 5.5 command line tool. I hav installed the .exe file.





But im unable to configure the compiler to run. I cant interpret the instructions in the readme file.





Pl help. i have completed step 1.





Installing and running the Command Line Tools


--------------------------------------...





1. Run freecommandlinetools.exe; choose the


drive and folder into which you want to


install the free C++Builder 5 command line


tool development system.





2. From the bin directory of your installation:


a. Add "c:\Borland\Bcc55"


to the existing path


b. Create a bcc32.cfg file which will set


the compiler options for the Include


and Lib paths (-I and -L switches to


compiler) by adding these lines:


-I"c:\Borland\Bcc55\include"


-L"c:\Borland\Bcc55\lib"


c. Create an ilink32.cfg file which will set


the linker option for the Lib path by


adding this line:


-L"c:\Borland\Bcc55\lib"

How to install Borland Compiler?
Ok, when step 1. completed it would have made a new folder. I will assume you did not change the name of this folder.





For step 2, part a.


If you are using Windows XP, go to 'Control Panel' (open it). Select 'System' (open it). Look for the 'Advanced' tab (select it). At the bottom is a button that says 'Environment Variables' (click on this). In the window that appears, you should see an entry for 'PATH'. Select this entry. Click on the 'Edit' button. Do not overwrite the text in here. What you want to do is to go to the end of the text in 'Variable value:'. Add this string without the quotes ";C:\Borland\BCC55\Bin" to the end of the PATH variable.


Note: There may be a 'Path' variable not a 'PATH', or even both 'Path' and 'PATH'. If you only have one, add it to the one. If you have two, add it to the one in the 'System variable' box/area.





If you are using windows 98, you can add to the path variable in the autoexec.bat file. This is usually located in the c: drive, and not in any folder You will need to right click (with your mouse) on the file and select 'edit' to be able to open it in a text editor. Add this string without the quotes ";C:\Borland\BCC55\Bin" to the end of the PATH variable. Ie, it usually says path=something;something\else;etc





For step 2, part b.


Create a new text file and rename it bcc32.cfg


To edit this file, right click (with your mouse) on the file (after selecting it). Then select 'edit'.


In this file you will need to add the lines mentioned.





For step 2 part c.


Create another text file and rename it 'ilink32.cfg'


Open it to edit as in the part b.


Add the lines mentioned.





Then, you will need to open a MS-DOS or Command Prompt box, if you use win98 or winXP, respectively. It is usually situated in Start -%26gt; All Programs -%26gt; Accessories





After opening the MS-DOS or Command Prompt, type in 'bcc32 -?" without the quotes into the command prompt. If all the above steps are successful, you will see a help message displayed.





Good luck.





[update] ps, you will need to add (create) those files in the 'C:\Borland\BCC55\Bin' folder / directory.
Reply:that happened to me. i just updated it
Reply:Try to check if your Command Compiler is in windows environment path


- Open Contol Panel - System


- On Advanced tab, click environment Variables


- In system variables, check if your c:\Borland\Bcc55 or c:\Borland\Bcc55\bin it's include in the path parameter, if not, edit and add the path.





Remember to check your command compiler wheter in c:\Borland\Bcc55 or c:\borland\Bcc55\Bin.

What is the code to print the extended ascii character set in c++?

I'm using borland turbo c++ if that helps

What is the code to print the extended ascii character set in c++?
I'd say just use a loop from 0 to 255, and print the integer converted to a character, like this:





int i;


char character;


for (i=0; i %26lt; 255; i++)


{


character = i;


cout %26lt;%26lt; character %26lt;%26lt; endl;

Plz plz plz any one tell me the program to compare two strings in c++?
Strings can be compared by using library function strcmp, for this header file "string.h" must be included. Function receive two string argument and returns 0 when string1 is same as string2, returns +ve no when string1 is greater than string2 and returns -ve no when string1 is less than string2.





Syntex:- int strcmp(char*,char*)


e.g.


#include%26lt;iostream.h%26gt;


#include%26lt;string.h%26gt;


void main()


{


char *st1="Ajay Kumar", *st2="Amit Kumar";





cout%26lt;%26lt;strcmp(st1,st2);


}





function will display -3 because second string is greater (according to alphabet) i.e. j - m = -3

this is the shortest simplest (least overhead) method I've seen for making a sleep function.





#include %26lt;time.h%26gt;





void sleep(unsigned int mseconds)


{


clock_t goal = mseconds + clock();


while (goal %26gt; clock());


}
Reply:Yeah, you can use sleep. If you are doing a console application, I see no other option. Otherwise, when you want to being processing you can keep track of time and spawn a thread. This thread simply compares the logged time with the current time, and executes a task after an hour has passed.

iam using borland turbo c++ 5.01 version and running on windows xp.

I am developing a code in c++ and in my code i need to run an application(an exe file) how can i do that.?
system(abc.exe);


runs the abc.exe from c++ code


spawn and execxxx may help too
Reply:In c/c++ there are set of functions like


%26lt;b%26gt;


exec


spawn


%26lt;/b%26gt;


and many of its derivatives which lets u run any .exe file from ur code.


They even provide more controlls like what the calling program will do till the called program runs.


U can even pass parameters to the called program.





Like u want to run note pad with argument "abc.txt" u need to call


%26lt;i%26gt;


spawnl(null,"notepad.exe","abc.txt");


%26lt;/i%26gt;


{


Obviously ur file abc.txt should be in the same directory or compleate path is required.


}


all these functions are defined in %26lt;b%26gt;process.h%26lt;/b%26gt;

Creating a parabola in C++?

I'm using Borland turbo C++, first off.


I need to create an illusion of a parabola, using a "for" loop.


I already have set up a coordinate plane with tick marks, and the program asks the user for the A,B, and C values of the quadratic equation. I just need some help on creating the "parabola". Should I use line function and make it so every so many few pixels are marked and eventually create curves, or what?

Any help would be appreciated :]

Creating a parabola in C++?
OK This was a fun thing to do and it is a little confusing until you understand where the screen coordinates actually are and what is needed to be done to flip and offset the values so that the drawn parabola appears correct.





I have 3 examples showing whats needed to be done to draw the parabola correctly, the comments hopefully explain my intentions.





I used putpixel() for the first 2 and the line() only on the last correct parabola as line() needs to remember the previously drawn points.





Good luck.

C++ Do-While Loop Question...?

Hello. :]


I'm using Borland Turbo C++, and making a program in which the user may enter an integer. Then, they are asked for another, and then shown the product of the two entered. They may continue entering integers, and the product will be modified after they enter another integer. The flag is 0, and th e program will terminate when the user enters it.





My only question is that during my do-while loop, what should I use as a variable, as far as what the user enters, so that when I do product=variable*variable, I get the answer, and not just product=num*num , whereas it'll just multiply the entered value by itself?





Thanks!

C++ Do-While Loop Question...?
Try this out in your code..





int product = 1;//starts at 1 so you can mutiply


int entered = 0;


int loops = 0;





do


{


cout%26lt;%26lt;"Enter an integer, 0 to stop"%26lt;%26lt;endl;


cin%26gt;%26gt;entered;


if(entered !=0)


product = product * entered;





loops++;


}while(entered != 0);





if(loops == 1)


product = 0;





cout%26lt;%26lt;"Product is "%26lt;%26lt;product%26lt;%26lt;endl;
Reply:If understand correctly you are asking user to enter the number and multily all the numbers until he enters a zero.





In do while loop put this code


product=product * num
Reply:well, after the initial product, your equation will actually change to product = previous product * integer. am i correct? so you could have two different variables like:


//input two integers at first, then put new integer into variable 2


product = variable1*variable2


variable1 = product


loop





i hope this helps, my c++ is a little rusty. good luck!

C++ Error?

"Possibly incorrect assignment in function Addition()"





I could post my code, but I rather just know what causes that error?





I can search for the error myself, if it means a specific thing is wrong, but I'm just wondering.





And, I'm using Borland Turbo C++, so you know.

C++ Error?
In the code from an earlier question you have this :





if(D=!C)





which sets D to the logical not of C, then the statement is true if D != 0. D and C are integers. I'm sure this isn't what you intended, and the statement should be this:





if (D != C)
Reply:Is this a run-time or compile error? Sounds like a compile error and the compiler is detecting a type mismatch or a potential bounds error. (e.g. you are assinging a float to an int, or a long to and int)
Reply:sorry i don't know.but i will ask my sis.
Reply:This is usually caused by making this simple mistake.





if (avalue=1)





// instead of


if (avalue==1)





In the first case you assign 1 to avalue and the statement is always true! DOH!





In the second case you test for avalue being equal to 1.





Look closely at your comparisons!

Drawing A Line --- C++?

I need to draw a basic line in C++, and if anyone could help, it'd be great.


If someone taught me how to create one line with tick marks, that'd be better, but I'd be happy with just being told how to draw one line. [Take in mind, that I don't want to prompt the user to draw a line, I just want to "print out" one to the screen.]


Thanks for any help with this :]





And by the way, I'm using Borland Turbo C++.

Drawing A Line --- C++?
hello,





it has been a long time since I used Borland so please bear with me.





Drawing a line on the screen may not prove to be very difficult. First all you have to do is to check for "graphics.h" if you have one.





If you have none, then I guess you have no choice but to use printf() function.





However If you do have, please check out the link that I am sending you. It is not a line (actually a circle) but has great explanation on how to do it :)





Take care and hope I have helped you.





PS : if i remember correctly, graphics.h also has a line() function with the following syntax :





line(xstart, ystart, xend, yend);





I am not so sure but you can try reading/scanning graphics.h for the command. Cheers =)
Reply:C++ has no native drawing abilities. If you are working in a console then the only way to simulate drawing is to use a output of "---------------" characters, otherwise you will have to move onto Windows programming to do any type of graphics work.
Reply:As farp says,, you can't drow a line in C++ environment, except if you wrote a code like this I think it will be possible :


[ cout %26lt;%26lt; "___________" %26lt;%26lt; end1 ]





or like this code





[ cout %26lt;%26lt; "---------------------" %26lt;%26lt; end1 ]

Parabola in C++?

Hi, I'm a 15 year old student, and I'm using Borland Turbo C++.


I have gotten one reply previously on this question, but I cannot exactly understand how to create a parabola based only on user entered values of the A, B, and C values.


Any help would immensly help.


Thank you~

Parabola in C++?
um, i guess it depends what interface are you using for your output.


if you use the command prompt, i would measure how many characters you can put in from the x and y axis that would fit the screen. then divide the x axis by 2, (if you want your parabola to be center at 0,0 and is a x^2 type. second you would make a for loop from -10 to 10. and type two marks that are X amt of distance between each other and symmetric to the x axis, and increasing to the X^2

}

Help with c++?
Looks like C code instead of C++, judging by the way the main function is declared without a return type. Not sure if it has anything to do with stdio.h though. Most c++ compilers come with it.





The C++ version would probably look like:





#include %26lt;iostream%26gt;


int main()


{


int n, sum=0;


std::cin %26gt;%26gt; n;


for(int i = 1; i%26lt;=n; i++)


{


sum+=i;


}


std::cout %26lt;%26lt; sum;


return 0;


}
Reply:Looks like c code. Try Dev-C++. The compiler that your computer is using probably doesn't recognize studio.h. I suggest dev-c++, the compiler is a lot better.


You can download it from the internet for free.


cheers!!!
Reply:Your compiler has not been installed correctly or you have changed where the compiler looks for its #include files.


Try reinstalling Turbo C++, that will fix where it searches for files #included.

Subroutines, C++?

Subroutines, C++?


Hello.


I'm using Borland Turbo C++, first off.


I'm using subroutines, and for the first choice, which takes you to the first subroutine, it'll go through and everything, and then it will return to the "menu screen" asking the user for a choice.


1 for Addition, 2 for Subtraction, 3 for Multiplication, 4 for Division, and 5 for Quit.





1 works perfect, and returns to the menu.


2-4 work fine, but at the end, it doesn't return to the menu.


5 works fine, and ends the program like it should.





Is there a reason that 2-4 do this? Are they supposed to automatically return to the "menu" at the end, or is there a way to make it return to the said menu?





Thanks =]





And, as asked, I'll post my code.


However, I'm just going to host the CPP file on mediafire, as it'll be hard to post on here, on the extra details part.

Subroutines, C++?
Before I give you a proper answer, I should mention that you're using both deprecated and non-standard libraries in this program which, unless your teacher said you could, will not give you a good grade.





The answer is quite simple... for whatever reason, before you do your looping test, you force all values of "choice" that are greater than 1 to be equal to 5. Think about this... you tell all values of choice greater than 1 to be 5 and then immediately you say "if choice equals 5, exit the loop". I didn't immediately notice any syntax errors that the person above me noticed, however, I did not compile the program. My first guess however is that he tried to compile it, didn't have conio.h, saw the errors and assumed you have syntax problems.





Charles, this is now the second time in two days that I've had to correct you. This guy is clearly doing this for a class, so why would you suggest changing the syntax when you don't even know what was taught in the class to this point? I mean, honestly... switch statements? Is that the only thing you can find worth changing in his syntax?
Reply:There're a lot of errors check your code





semicolons and the brackets check them
Reply:You might try the switch/case to do this, but don't change the value of choice - code looks nicer this way.





Also, you should get rid of clrscr(). It's platform specific, and doesnt work for most people. Including conio - Just get rid of conio... (Hope your class doesn't require clearing the screen, if so - ask them why? You'll never use that in a future job, the old pkzip never cleared the screen. )





main(void)


{


int choice;


do{


//clrscr();


cout%26lt;%26lt;"1. Addition\n";


cout%26lt;%26lt;"2. Subtraction\n";


cout%26lt;%26lt;"3. Multiplication\n";


cout%26lt;%26lt;"4. Division\n";


cout%26lt;%26lt;"5. Quit\n";


cout%26lt;%26lt;"Choice: ";


cin%26gt;%26gt;choice;





switch (choice) {


case 1 : Addition(); break;


case 2 : Subtraction(); break;


case 3 : Multiplication(); break;


case 4 : Division(); break;


case 5 : break; //do nothing


default: cout %26lt;%26lt; "Invalid Choice\n"; break;

Go to borland website and post a question regarding this problem. But most probably you need to update your libraries files the .h extension. most likely it is the IDE(intergrated development environment) that contain the compiler that did not work try buying a new one or using an open source IDE like http://www.bloodshed.net/ If you want make a donation. :)

C++ Program Help?

I'm using Borland Turbo C++.





Okay, here's my code:


http://www.mediafire.com/?0hnrz1nxm31





Apparently, I have to use long ints or something


to limit my numbers for my fraction subroutine, as far as multiplication and division.


I need to figure out how to limit it.


It seems okay with easy,


but when it gets to medium and hard,


it shows my numerator as - [number here]


.


For medium I can go from 1-99.


For hard 99-999.








And for decimals, I have to


make the numbers larger for medium and hard.





Any help correcting my code would be greatly appreciated.





Thanks~





And, if you completely correct my code and host it.


or tell me exactly where to put whatever snippets.


I'd greatly appreciate it.





This is due in two days, and I have no clue


what to do past this %26gt;_%26lt;

C++ Program Help?
If you're using cout, you should be using endl instead of embedding \n in your strings.





You only need one temporary variable to swap two numbers. With A and B, do C = A, A = B, B = C.





I don't know if Turbo C++ uses 16 or 32 bit ints. If they're 16-bit, then you could possibly overflow because you have ANum=(A*B1)*(A1*B) where A %26lt;= 26, B %26lt;= 50, A1 %26lt;= 25, B1 %26lt;= 50. Using the maximum values gets you (26*50)*(25*50) = 1,625,000 which is way more than the signed 16-bit limit of 32767. Use "long" instead of "int" and keep trying.





A good code pasting site is http://pastebin.com/
Reply:Wow!!! The reason why ur r confused is the fact that ur using too many functions.





For eg





Have three functions namely:





void lvl1(char op) // op can take '+', '-', '*' or '/'


{


.............// Randomize


.............// whatevr loop





.............switch (op)


.............{


........................case '+' : ans = a + b; // Whatevr variables used


.........................................


........................// Similarly for others

............. // Get Answer and check using simple if





}





Similarly for other levels


void lvl2(char);


void lvl3(char);





and u cud also use only 3 random generating subroutines for l1, l2 %26amp; l3





After this try analyzing the problem, the solution comes to you automatically......

I'm very new to C++. Can anyone tell me why this function doesn't work?





bool UnlockDrive(char PW[70])


{


if (PW!="") {


char ExecString[350];


ExecString = "";


char sys1[90];


sys1 = "start \"mount.exe /v locked.dsk /l z /h n /c n /p \"";


char sys2[90];


sys2 = "\" /m rm /q\"";


strcat(ExecString, sys1);


strcat(ExecString, PW);


strcat(ExecString, sys2);


system(ExecString);


}


return true;


}





I'm using Borland Turbo C++ version 10.0. I get the following error when I try to build the application:





Lvalue required





It is referring to the lines:





ExecString = "";


sys1 = "start \"mount.exe /v locked.dsk /l z /h n /c n /p \"";


sys2 = "\" /m rm /q\"";





Any help would be greatly appreciated!

Help in C++?
ExecString, sys1 and sys2 have their size declared, I think you need to set them to a string literal containing the same number of characters. What you can do is this instead:





char *ExecString = NULL, *sys1 = NULL, *sys2 = NULL;


sys1 = "start \"mount.exe /v locked.dsk /l z /h n /c n /p \"";


sys2 = "\" /m rm /q\"";


strcat(ExecString, sys1);


strcat(ExecString, PW);


strcat(ExecString, sys2);


system(ExecString);
Reply:Since u r using C++ use standard library's string class std::string instead of char *:





using namespace std;


std::string execstring;


execstring = "" ....


system(execstring.c_str()); Report It

Reply:The problem is ExecString="". This is in conflict with the definition just one line above.





There are many ways to fix this.


(1) If you change that line to strcpy( ExecString, "" ) you should be fine.





(2) Or you could eliminate that line change the strcat(ExecString, sys1); to strcpy(ExecString, sys1);





Good luck!

What is the code in c++ if i want to type r and it will run or type esc it will escape. Im using Borland 3.0?

Im using stdio.h conio.h etc but im not using iostream. we have a project called the game of life! we have the formulas loops and etc. but we dont how to do the "press esc to exit press r to run press space to create cells and blah blah"

What is the code in c++ if i want to type r and it will run or type esc it will escape. Im using Borland 3.0?
Use the ISO std function getch() to get the next input character and return its value. Pressing the space bar will cause getch() to return 0x20 (32 decimal.) The escape key: 0x1b (27 decimal.) Lower-case r: 0x72 (114 decimal.)
Reply:This may be pseudocode... but hey, it's been a while for me :-P





something like:





if (Asc(getChar()) == "r") {


//code


}





or maybe a "keyDown" callback function or something
Reply:If you do a getchar() from standard input and compare the result with 'r' and ' ', won't that work? I don't know what you'll get for the escape key though. Will it be the ASCII code for ESC '\033' I think but i can't remember.





The only thing is that input from a keyboard is typically line oriented, i.e. you have to hit the enter key before your input is given to the program. There are system specific ways of changing this behaviour so that your program gets each character as it's typed. You need to consult your system documentation for this.

Where can I get a program that allows me to write c++?

I would like Borland c++ version. I think it has to do with Turbo, maybe? I'm looking for the program that allows you to write the souce code and then you press execute and it will compile it and run it. I don't know what to call this type of program though.

IDE %26amp; Compiler. Here ya go:

EDIT: Integrated Development Environment - where you type the program in - typically w/quick compile, link, %26amp; run. (And in some cases form building resources.)





Depending on what you're looking to do (either console [DOS/Unix-Linux Command Line] or Forms) you could just stick with the MS C++ 2008 Freebie compiler from that list.





Borland is still viable if it's on your mind to use it, especially the DOS [turbo] version. (I think there's a free version on that list as well.)

What is "using namespace std;" in C++??

what does it do? Is this code a recent addition? I had started C++ 2 years ago and then switched to java .Back then nobody tought me to use it("using namespace std;") ever not even once.Was my teacher dumb??


and the compiler i use says"Namespace name expected " every time i include this peice of code in the program.The compiler i use is Borland C++ version 5.03 .Is it a source of the problem??help me out guys.

What is "using namespace std;" in C++??
Without getting too complicated -- basically they have created a way in C++ to differentiate between different areas of "namespace" in such a way that you could potentially have multiple objects or typedefs, etc of the same name that don't overlap. The "std" namespace is where most things in the C++ header files (iostream for example) live.





For example I could create a class and call it "string", even though a class called "string" already exists, if I put it in a different namespace.





I would guess that you are using something like a cout, cin, endl, string, or other predefined type/object. "cout" for example is actually called "std::cout", but by putting "using namespace std;" you are able to leave off the "std::" part.
Reply:"namespace" is the essential part of C++. To understand what any namespace means (as e.g. namespace std), just read any C++ book.
Reply:some classes etc. are declared in _namespaces_, std - is one of that nmespaces. To access that class you need resolve the namespace.


Taht could be performed with: using namespace xxxx; (as an option)


For instance:





#include %26lt;vector%26gt;


#include %26lt;map%26gt;


using namespace std;


....


vector%26lt;int%26gt; v;


map%26lt;int,int%26gt; m;


********************** or *****************





#include %26lt;vector%26gt;


#include %26lt;map%26gt;


....


std::vector%26lt;int%26gt; v;


std::map%26lt;int,int%26gt; m;

good luck
Reply:You might like to read this for a decent introduction to namespaces:

Well u need to know how to make the dll workspace to work in it right ?





in your vc++ open new project and choose dynamic link library .. then import all you cpp and headers files into this new project .





finally just remove the default cpp file created with the new project that u don't need it anymore , and save yourworkspace and you can start compilation now .
Reply:Does it need to be recompiled? One of the strengths of DLLs is their reusability - you can write a DLL in C then import it into pretty much any language and use it quite happily, and this normally doesn't mean recompiling.

just make a loop thats ends after 1 turn, and add the following:





printf("*");


printf("**");


printf("***");


printf("****");


printf("*****");





send me a message if you fail to do so
Reply:I'm not sure of what notions you have to apply to this, but I will suppose that you will have learned how to a) print to standard output, and b) use loops.* I'm also going to suppose that the format of the output is written from left to right, top to bottom, in the terminal/prompt.





You will have noticed one of a number of things from looking at the output : the number of asterisks ('*') on a given line is greater than the number of asterisks on the previous line. Basically, the number of asterisks on a given line increases as the depth of the line increases.





The first thing is to print the asterisks. We cannot print them directly, given that the number of asterisks varies per given line. However, we know that the number of asterisks is equivalent to the depth of a line (!!!!). In pseudo-code :





for i = 1 to depth do


print('*')


end_for





Great ! We now have the asterisks figured out. Now that we've focused on a line, let's focus on the whole of the triangle. Again : the number of asterisks in a line is proportional to the depth of that line. This means that the depth will increase as we add more lines. An increase in lines, and increase in asterisks...yet another loop :





/* to print depth lines */


for i = 1 to depth do


for j = 1 to i do


print('*')


end_for


print('\n') /* let's not forget to go to the next line */


end_for





In C++ that would give something like this :


--------------------------------------...


#include %26lt;iostream.h%26gt;


using namespace std;





void print_triangle(int depth)


{


int i;


int j;





for (i = 1; i %26lt;= depth; i++)


{


for (j = 1; j %26lt;= i; j++)


cout %26lt;%26lt; '*';


cout %26lt;%26lt; endl;


}


}





int main(void)


{


print_triangle(7); /* play with this value */


return 0;


}


--------------------------------------...


Check the includes, but this should work fine. I hope this helped.


Good luck on you exam.

* If you haven't used loops, then simply sequentially printing the lines.

But u can't see the last 2 statements (showed in block)....here what actully happened is ...





The destructore for obj2 will be called after the "MAIN() FUNCTION" is terminated" (i.e. after the closing braces).


B'coz, obj2 is declaired in main() function, so its life is in the main() function's scope.


The destructor for obj1 will be called just b4 the "PROGARMM" is terminated (i.e. bust b4 the programm is removed from the memory).


B'coz, obj1 is a globle object of TEST class and its life is thruout the programm.





I dont know about the Borland Compiler, but in Turbo compiler you can se the output screen again after termination of the program using "ALT + F5" and doing this will show the real output...

A class can ONLY have one deconstrutor. Also if you are compling this in one file...as your code showed...then why did you not use namespace std?

So, you might have an issue with text output. That doesn't explain why you get some lines printed out and not others, though. So, yeah, you might also have a flaky compiler, since the code works as expected with g++.

Reply:First, you need to contact the lifeforms of the Vega star system. Request the proper file bytes from them. After a short period of time (a little over 50 years), you will receive the bytes of all necessary files from them in binary. Make sure to account for atmospheric interference if you're using a common radio frequency. Once you have the data, open your hex editor (you do have one, right?) and input the bytes one at a time. When you're finished, you should be able to use the compiler. You might need to do a few manual registry updates. Oh, and I think Vega is pretty trustworthy, but it couldn't hurt to run a virus scan on the file once you're finished downloading it. Vega might be planning something.

From Where I Can Download "ANSI-C++ & C++ 4.0" ?

Also Tell Me What Is The Difference B/W "Turbo C++ %26amp; Borland C++" ?

From Where I Can Download "ANSI-C++ %26amp; C++ 4.0" ?
You do not download ANSI-C++, you download, or buy an ANSI-C++ compiler or Intergrate Development Environment (IDE).





You have to create a text file that contains the source of the c++ program you wish to make, an very simple one below:





include %26lt;iostream%26gt; // For writing to the screen / console





using std::cout; // To get the output stream


main()


{


cout %26lt;%26lt; "Hello Danishahmed25pk";


}








Thats the end of the program, save it in a text file with the extension .cpp





You will then need to compile it using the compiler or IDE you have.





Borland offers a free compiler [1] details at [2]. There is also a purchasable compiler on the page at [1].

"Turbo C++ version 1 was our first compiler that supported the C++ language. The C++ compiler conformed to AT%26amp;T's 2.0 specification for the C++ language."[3]





It appears the Turbo Debugger is still used on the free Borland C++.
Reply:Turbo C++ is the old Borland C++ compiler!

C++ mutual-inclusion (mutual dependcies)?

Hi all. I am having an issue using Borland C++ Builder where I have 2 classes:


TTarget


TTgtMgr





Both classes include references to the other in the defintions (header) and the implementation (cpp)





I tried using forward declarations. This allows me to make vars


TTarget *tgt


TTgtMgr *mgr





in each others classes, however the problem is, in the implementation, I try to access the methods of the other class and I recieve the following compiler error:





Cannot access methods of %26lt;class%26gt; because %26lt;class%26gt; is not yet defined.





So for example in TTarget.cpp I do:


*TTgtMgr *mgr


mgr-%26gt;someMgrFunc();





And the error occurs.





I feel like some form of late binding might help but I really dont understand it well enough to implement such a fix.





Any thoughts on how I can remedy this problem?





Thanks!

C++ mutual-inclusion (mutual dependcies)?
In the .h files of the above two classes use forward declaration, no "*" required.





In TTarget.h before actual class definitions starts








/////////// TTarget.h file





class TTgtMgr; //forward declaration





class TTarget{





}








/////////// TTgtMgr.h file





class TTarget; //forward declaration





class TTgtMgr{





}





fill in the rest of the implementations

C++: how to create a .lib file?

Hi i have a simple console program done using Borland C++.


How do i cut portions of it and make them into .lib and .h files?

C++: how to create a .lib file?
In Borland, depending on version, there should be a command line tool called TLIB that actually installs the object code and certain parameters into the .lib file for you. As far as I know, you need to do these steps:





1). As posted by others, leave out the main function. Everything that will be called as a library routine should have a function definition ( the complete function ) left in the .c source file.





2). Be sure that all function declarations are put into a header (.h) file and that any included headers are included there also. Be sure that any global variables are either exposed by declaring them as external or transferring them into the source (.c) file.





3). Make sure that all the functions names are unique among standard libraries so there won't be name conflicts later.





4). Compile your two files to object (.obj) files.





5). Instead of linking them with the linker, simply use the TLIB.EXE utility that comes with Borland products to produce the actual library file. Keep a copy of the source! You might want to revise it later.





6.) Optional step: write another project to test calls to each function independant of the original source code, compiling with the appropriate header and library files as options.





I believe that I covered everything. It has been a while since I've written any libraries in C or C++. Hmmm... maybe I'll just do that! Thanks for the idea.

Do I need C++ turbo to write programs? Can I download this type of program?

I would like Borland c++ version. I think it has Turbo in the name of it. I don't know what to call this type of program though. I'm looking for the program that allows you to write the souce code and then you press execute and it will compile it and run it.

You can use any IDE. Take a look at Eclipse, which is a free, open source IDE - http://www.eclipse.org/
Reply:No. You can use Notpad for write a program %26amp; just save it with .cpp extention.
Reply:No, you can use any type of C++ compiler.


If I were you I would get Dev-C++;

Basic C syntax, assigning a value?

I am working with Borland C++ 5.02 compiling a C program to read an INI file with this function prototype:





extern const double readIniDouble( void *fp, const char *section, const char *name, const double defValue );





I can read the value with no problem with this code:





double test;


test = readIniDouble( iniFile, "ASection", "AName", 2 );


cprintf( "%e", test ); // Correctly writes the default value of '2'





The problem is that I need to get the value into a struct:





static struct settings tmp_set;


tmp_set.aSetting = readIniDouble( iniFile, "ASection", "AName", 2 );


cprintf( "%e", %26amp;tmp_set.aSetting ); // does not work





This compiles but prints an unexpected large number. If I use an ampersand or asterisk in front of tmp_set on the left side of the assignment (%26amp;tmp_set.aSetting = ... ) I get a compiler error 'Illegal use of floating point'.





What is the correct syntax to assign the return value of the iniReadDouble() function directly to the struct member?

Basic C syntax, assigning a value?
don't print %26amp;tmp_set.aSetting, just tmp_set.aSetting. With the %26amp;, you're taking the memory address of that variable, not its value.

Turbo C++! How can i make the char statement recognize two characters at the same time?

This is for my assignment in our basic programming class. we are required to make a program like those in television. Where the computer displays a list of channels then prompts the user to input a channel (it could be a letter or number). then the name of the channel will be displayed on the screen. i used the data type "char" so that i could work on both letters and numbers. but char only recognizes a single character. how can i make "char" recognize two characters on a single variable? by the way i am using borland C++(TURBO C++ IDE) thanks..

Turbo C++! How can i make the char statement recognize two characters at the same time?
I guess you could use either a character array or a string. If you know you only need two characters then I would go with the character array.





char channel[2];


channel[0] = '1';


channel[1] = '0';


element 0 is the first character and element 1 is the second.
Reply:I too would use a char array.


char channel[2];





channel[0] = '1';


channel[1] = '0';





OR


channel[0] = '7';





The use a string array for the channel names


string name [10] will hold an array of 10 strings.


so name[0]='ABC"; etc





Then use the atoi function to change the char array to a number. (atoi is a function that takes a constant char pointer (char array variable) and converts the entire char array to its integer equivalent)


So, if the char array is ['1','0'] it would be 10 in int


Then that 10 can correspond to the 10th index in the string array, which could be whatever, CBS.





Like this


int x = atoi(channel);


String tempName = name[x]; //get the string name





Meaning you have two arrays where there index corresponds to one another.

C++ help??

I compile a project its got no errors!


but when running it i get linker errors!


how to solve it?


i use borland c++ and dev c++!

C++ help??
It is impossible to tell without seeing the error but most likely you have a method or static member defined that you did not provide an implementation for. This problem can only be caught at the link stage. Other possible problems are a missing library, the wrong library, or a misdefined remote call.





The compile stage builds the individual pieces. The link stage glues them all together. It is not until the link stage that it can notice that something is missing.
Reply:just go to file save as another filename then compile


most of the time this solves the problem

A good C++ compiler?

Hi! I'm quite new to programming in c++ (NOT VISUAL C++) . I am currently working on Borland C++ v3.0 (Dos version). I wanted to know if there is a compiler with similar code but is window based i.e. the IDE for it is a window and not the dos screen for it utilises too much of CPU. Please reply and possibly give a download link for a free compiler of this sort. I'll be grateful...

You’ll see two major recommendations over and over, which are good choices for beginners. The first is Visual C++. On a windows PC this is ideal. You can get a free version. Google for Visual C++ Express.





The second is gcc. They make a C++ compiler. The windows version is under the name MinGW. Bloodshed Dev-C++ and many other IDEs use MinGW.

Is it normal for my c++ software to get my processor working at full power?

I have the Borland C++, and because of the heat the processor goes over the hedge. When I start the IDE the processor climbs up to 60 Celsius and then the Windows give's me the blue screen. Is it normal for C++ to put this much presure on my cpu? I have a AMD Athlon 3500+/ 2 Gb Ram/ Asus Mb. So the system is not a weak one. The borland software has been used by my highscholl for about 15 years, from my teacher I got it to work at home. Could the problem be that the software is too old?

Is it normal for my c++ software to get my processor working at full power?
The IDE is sitting on a 'busy-wait', the application seems to be that old!





http://en.wikipedia.org/wiki/Busy-wait





Run it in Dos-Box, that will regulate the speed.





http://dosbox.sourceforge.net





Or you could use a newer IDE instead. Your C++ compiler should still work, but it's really old, and your programs will suffer the same fate as the IDE!





This is the best free IDE/GNU G++ based C++ tool chain I can find:





http://www.bloodshed.net/dev/





About the compiler:


http://en.wikipedia.org/wiki/G%2B%2B





(Dev-C++ uses the GNU compilers, it's used to compile most Open Source applications, including some Operating Systems! It will also use the features of your processor, where the old Borland compiler wont - a new Borland compiler will of course. To find out why the IDE failed, look into the following functions - sleep, and usleep! - have fun!)

Reply:Borland C++ consuming too much CPU on a 2gig Box, amazing!


I guess the SW is corrupt. Why dont you re-install Borland C++ and try again?





Get the latest Borland C++ SW. If you are using the old one (from your school days), its designed for DOS and 80*88 processors. That should be the problem.





Alternately, you can run the C++ IDE (If it is DOS based) in command window launched by "cmd" command - not "command" command. Try this.
Reply:The only thing I can think of is that you're running a console application in DOS. To deal with that use DOSBox or something similar to underclock your machine. Seems odd though!

For C language programmers that also know Linux...?

Does Linux (for instance Fedora Core 5) provide a good IDE for C language programing? One that you personally used and liked. One that you can say it is good.





I already have Fedora Core 5 installed on my PC, but I don't know where to look for a C language IDE in this version of Linux.





I am also a quite bad user of Fedora Core 5 (I mean I don't know how to set up an ethernet card, or an internet connection... the installation does it automatically... or I don't know how to mount my HDD without looking at something I wrote in the past about this... or other stupid things that Linux makes you to learn...)





I need DEBUGGING immediately... I have an old Borland C 3.1, and in WinXP it says it can't start the debugging section of the IDE on 16 bits... It can only edit and compile, but no debugging, unfortunately...


What to do?

For C language programmers that also know Linux...?
Anjuta is the best IDE available.


It works pretty well.





For debugging you can use gdb also(if you don't mind working on the console)
Reply:Linux doesn't support IDE version of C, it has in-built GCC compiler. (Though I've RedHat platform, not Fedora). You can partition your HD to accomodate both Windows and Linux both operating systems in your computer. Then install Turbo C++ IDE in Windows part .
Reply:"Does Linux (for instance Fedora Core 5) provide a good IDE for C language programing?"


There's a few IDEs that run on Linux. http://en.wikipedia.org/wiki/List_of_int... gets you a list of IDEs. KDevelop and Anjuta, and I think Code::Blocks are usable on Linux. It's also not uncommon to see people prefer to use a plain text editor and use commandline/makefiles for compiling and linking.





The compiler on Linux is gcc and g++ (for C and C++). The debugger that goes with gcc is gdb.

C++ environment for mandriva?

i've been stuck on finding the solution of this problem :


before this, i use borland C++ 5.2 under XP, however now i used linux mandriva 2007.1 one spring. the quiestion is, what is an equivalent software to my previous compilers. I've used Kdevelop but found myself stuck to make a console application. Someone please help me. I also used WINE to run that borland. But the application won't appear when i tried to run it under mandriva.

C++ environment for mandriva?
everything's already there.





create a file called i.e. test.cpp, then compile it in a console:





g++ test.cpp -o test





now you can start it with


./test





if you omit the parameter "-o test", then the created file is called a.out.

What is difference between c++ & embedded c++, do they require different version of C++ for prog. execution?

i know a bit of embedded %26amp; assembly language,but still dont know difference between c++ %26amp; embedded c++. i have a progg in c++ for serial communication but now i dont know whether i have to run it on normal (borland) c++ or it require some other version of c++.plz do tell me the source if it require some other version

What is difference between c++ %26amp; embedded c++, do they require different version of C++ for prog. execution?
They are basically the same as far as language goes. The biggest difference is going to be the compiler and operating system. If you have a serial communications module written for an embedded processor, it probable wont work on your desktop/laptop, or the other way around. Mostly because of the operating system used on each.

C++ programming, Error E2194; could not find file hello.cpp?

I am trying to run a simple program and I've installed Borland C++ compiler for free on my computer. The code is supposed to simply write Hello World, on the screen in the command prompt box. The book I have tells me to type in bcc32 hello.cpp into the command prompt box to run the program, but I get the error message. It recognizes the bcc32 command, but then runs the E2194 message. I had to change the path in environment variables first since the bcc32 was not recognized at first, but after changing the path, this works. I have also created the two necessary text files bcc32.cfg and ilink32.cfg. The path is c:\Borland\Bcc55\Bin. I have the hello.cpp program in what I think is the right spot, but it seems to not be able to find it. Can anyone help me. I need to know how to tell the computer or program where to "look" for this file.

Borland is outdated!





Get a better compiler, like Dev-C++ (it's free, see sources).


Once you've installed it, click File (toolbar) %26gt; New %26gt; Project...


From there it'll give you a few program types.. (you can click the 'Introduction' tab for the Hello World example).

If configured correctly, it should be looking for the hello.cpp file in the current directory. If not, try fully qualifying the program, that is:





bcc32 c:\blahblahblah\hello.cpp





If that works, then you've got a configuration issue. Something should be set to check the current path first.
