The challenge is checking for correct operation, so error-free compilation isn't enough to pass the challenge.

In this case, you have structured your loop in a way that prevents the program from ending.

A program built according to the instructions will prompt and accept input one time, and based on the input it will either print "Yay!"s or an error message. Either way, it should end.
