Problem with looping back to the previous question when user makes bad input
I’m creating a very simple interactive program where a user selects the type of Drink, Side, and their sizes. The program works but I was wondering if there is a smarter way to have everything in one while loop. The reason I have a while loop per user-prompt question is because I want to ask the previous question again until the user makes a valid input. I couldn’t think of a way to have this same functionality in one while loop.
