    You write them and then you save them as .h extension files. then you include them this way
    Code:
    #include "my_header.h"

    Any good IDE (I use Dev-C++) will allow you to create and save header files. They are like .cpp files except that they don't contain a main function. They are used to store variables, functions, and structures.

    This works:
    Code:
    /* header.h */
    #include <stdio.h>
    
    int main ( void )
    {
      printf ( "Hello, world!\n" );
    
      return 0;
    }
    Code:
    /* main.c */
    #include "header.h"
    It's important to realize that headers are nothing more than a convenient way to organize text that's to be pasted into your code.
    My best code is written with the delete key.

    Prelude: I did know that, however a)I didn't want to confuse him (you won't usually see a header file with main) and b)I didn't really have another way to say it.
