This is where you use a function, but declare it below the place of  
calling:

address@hidden:~/p/warn/1$ cat main.c
#include <stdio.h>

int
main()
{

        p();
}

void
p(void)
{

}
address@hidden:~/p/warn/1$ gcc main.c -o main
main.c:11:1: warning: conflicting types for ‘p’
main.c:7:2: note: previous implicit declaration of ‘p’ was here
