In another .c file, which you will compile separately and link later. Example:

--file func.h--
int my_function(void);

-- file func.c--
#include "func.h"
int my_function(void)
 {
  /* body of function */
 }

--file main.c--
#include <stdio.h>
#include "func.h"

int main(void)
 {
  printf("%d\n", my_function());
  return 0;
 }

To compile this:
gcc -c func.c
gcc -c main.c
gcc -o prog.exe main.o func.o
