Problem Description and Given Info

You've been asked to develop a point of sale system for "Patty's Cakes", a popular cupcake bakery in town. The program should allow users to order a pack of cupcakes, select flavors from a menu, and compute the total cost of their order.

"Patty's Cakes" specializes in cupcakes. Customers have the option to buy a 4-pack or a 6-pack of cupcakes. Each pack can be filled with a variety of flavors, with each flavor priced differently. Your task is to create a program that guides the user through their cupcake selection and calculates the total price of their order.
