Needing help with c++ loops

[Purrenhage]

I am learning C++. This class project was to write a program that will let you enter a diver's first and last name and city. Also 5 judges results along with the difficulty for the course. Then display the results. It is suppose to ask if you want to enter another diver. I cannot figure out why it is not looping the program at the end.

Here is the error I get back
