First off, fflush(stdin) is undefined behavior. Secondly, you have many newlines still in the buffer after your while loop; read: How to get my program to wait for a keypress-FAQ. Pay particular attention to flushing the input stream.

Now, your implementation defined fflush() is in the wrong place for your loop based on what you want it to do.

Pay close attention to the spacing...

     scanf(" %c",&choice);
    } while (toupper(choice) != 'Y');   
    return 0;
