C++ Code Help !! . I am having few problems in the checkout function

1. After the bill has been displayed it should return to the main screen when I press on any keys but currently the bill is displayed again and again.

It will be of great help if anyone could correct my errors and send the source code.I compiled this code using code blocks Thank you in advance!!
