You can make one like this...

// file1.c
int return_a_number(int i,int i2)
{
return i+i2;
}
// end

// header.h

#ifndef __HEADER_H__
#define __HEADER_H__
int return_a_number(int,int);
#endif

// end

// mainfile.c
#include "header.h"
// C++
// #include <iostream>
int main (void)
{

// print or count, whatever...
// C++
// cout << "1 + 2 = " << return_a_number(1,2) << endl;
// C
// printf("1 + 2 = %d\n",return_a_number(1,2));

return 0;

}
// end

then compile (if you are not using rhide)
gcc mainfile.c file1.c -o output.exe
or if you want to optimate:
gcc mainfile.c file1.c -o output.exe -O3 -ffast-math
(in that program it would rather not so useful to optimate, but...=)
