Creating a header file

[task]

Hi, I am currently studying 'C' and I was just wondering how do I create user defined header files.

[Dr. Bebop]

Just create a file with a .h extension and throw declarations into it.

/* header.h */
/* Inclusion guards to make sure the header
    is only included once. Any more is an error */
#ifndef BIG_NASTY_MANGLED_NAME__H
#define BIG_NASTY_MANGLED_NAME__H

#define TRUE (1==1)
#define FALSE !TRUE

typedef int bool;

void function();
int another_function( int, float );

#endif
