C++ Code Help!! In the checkout function, after the total bill is displayed, it's supposed to return to the main menu when I press any keys but then it keeps on displaying the total bill for a few times. I have pasted the output below.

It would be of great help if someone could correct my code and send the corrected source code. Thank you in advance !!
