#include <stdio.h>  
int main()
{ 
   char cResponse = '/0'; 

   printf("/na/tTurn the AC on/n"); 
   printf("b/tTurn the AC off/n"); 
   printf("/nEnter your selection: "); 
   scanf("%c", &cResponse); 

   if (cResponse == 'a'){ 
      printf("/nAC is now on/n"); 
   }
   if (cResponse == 'b') {
      printf("/nAC is now off/n"); 
   }
}
