Not very sure, but try this :

#include<stdio.h>
#include<conio.h>

 void rep();
 int main()
 {
     clrscr();
     printf("Hey! Please press 'a' to exit...\n");
     rep();
     getch();
 }

 void rep()
 {
     printf("Hey\n");  
     if(!kbhit() || getch() != 'a') rep(); 
     clrscr(); printf("bye"); return;
 }
