In-N-Out Receipt Generator
This is pretty cool! I think that it could be improved by providing a list of options, and you pick out an item and input the number you would like, and then it brings you back to the list. It keeps track of the items, and then when "end order" or like is inputted, it then calculates the receipt. If an invalid item is inputted, just output "invalid input", and then return to the list?
