Creating a POS System in C++ with multiple menus. For example:

Home menu: In this problem, The POS system will have two different sets of menus. One menu is for the customers who come to the store to buy products. The other is for the administrator who runs the store. Imagine that the store runs by the administrator who can add new products and is interested to see report at his/her discretion. Therefore, you need to implement the initial menu as follows: 1.Customer 2.Admin

If option 1 is selected, your program will return the previous three menus (Customer menu) as follows: 1.Sale 2.Pay 3.Exit

Customer Menu: Option 1 = Sale: Sale mode will enable the following categories(category menu) 1.Bakery 2.Fruits 3.Grocery 4.Vegetables

Just trying to build a simple POS system with multiple levels of menus and an option to buy a number of products under the "Sale" menu and the user can select what they want then another menu to pay for the items. I'm very lost of how to create menus in a level sense so any help would be greatly appreciated!
