How to setup visual c++ 6.0 to compile and run a C program?

I'm trying to build and run a C program in Visual C++ 6.0 but, even if my code is correct (I copy-pasted it from a reliable source), I still get errors. I remember that my teacher instructed us to configure the IDE such that it compiles a C program but I don't remember how it was done. Please help! Really urgent!

> even if my code is correct (I copy-pasted it from a reliable source), I still get errors
As a newbie, how would you determine what a "reliable source" is?
And post your actual error messages.

Well making sure you name all the source files as prog.c (and NOT prog.cpp) is one way.

Code:

---

#include<stdio.h>
#include<conio.h>
main()
{ 
  textcolor(RED); 
  cprintf("C programming");   
  getch(); 
  return 0;
}

---

warning C4013: 'textcolor' undefined; assuming extern returning int
error C2065: 'RED' : undeclared identifier

I already changed .cpp to .c but I still get the same error.

Heh, reliably obsolete is what that load of rubbish is.

<conio.h> is not a standard header. Functions and constants within it (textcolor(), RED, cprintf(), and getch()) are also non-standard, and not supported by most compilers.

You also need to specify explicitly that main() returns int (i.e. "int main() ...."). That is deprecated in C, and usually considered bad practice. When compiling as C++ (e.g. with a .cpp extension) it will give another compilation error.

This means that most of the lines you have obtained from your "reliable source" are invalid. Visual C++ 6.0 is not exactly the most modern compiler, but the error messages it is giving for that code are completely appropriate.

Lol, you have three function calls, none of which are supported by standard C.

- Get rid of textcolor (use ncurses if you really want that functionality).
- Change cprintf to just regular printf.
- Change getch to getchar.

Oh. I see. I said it was reliable because it was recommended by our teacher. Thank you for the tips and info.

Perhaps you should have started with the most basic "hello world" style program to test your compiler:

Code:

---

#include <stdio.h>

int main(void)
{
    printf("I like cats.");
    return 0;
}

---

The best part - if you understand Chapter 1 of any 'C' book, you could write this yourself and bypass the copy + paste method for such a simple test.

those are TurboC (ancient obsolete compiler) specific functions. s this where you got the code? textcolor in c
if your instructor said to get it from there, i don't know what to say.
