Question

Level 3 - Create a menu with toppings and able to order multiple items with the choice of 1 topping (max grade 95/100): a) User may enter any number of menu items and each menu item the user can choose the number of toppings (minimum 2). b) Once all the menu items and their toppings are entered, the program will take the order. c) The customer can only pick 1 of the toppings for each of the menu items they choose. d) User may choose to run the whole program again. (Therefore, they create a new menu and take new order.)
