Question

This assignment requires the development of C++ software that supports order processing, account management, and inventory control activities of an imaginary food service. Assume that customers of this food service will use a separate Web-based app (not included in this assignment) to browse product catalogs and then create shopping lists stored in specially formatted text files (see input definitions below). Each shopping list may include:

• Food item names and quantity.
• Coupon information that includes the name of the food and discount amount.

To process these shopping lists, customers must first create an account with your service. Each account is identified by a unique customer id and maintains an amount of money that may only be used for food purchases (i.e., a debit account). Customers enter a dollar amount when the account is created. Once they have an account, then they may select one of the following actions provided by your service program.

• Retrieve a shopping list file and save it to a virtual cart (only one virtual cart per customer).
• Retrieve a saved cart.
• Add or remove items from a saved shopping cart
• Create shopping cart reports (output text file with list of saved cart items for a specific customer).
• Process the current cart (checkout). Saved carts must be deleted after checkout.

Also, customers must be able to perform the following basic functions on their account.

• Add money to their food service account.
• Display account information.

The inventory for this food service must be controlled by a food service manager. Your application must provide the following functions for the service manager.

• Addition of food item quantity to the inventory of the food service (i.e., re-stocking).
• Prices changes for food items. (Note: Official prices are stored in the inventory – not shopping carts).
• Creation of inventory control reports (for the entire inventory or selected items).

Therefore, the main function of your application, must prompt the user for the following actions using a simple console window.

1. Login or create an account. (Service manager account must already be in your system.)
2. If service manager,
   1. Add quantity to inventory.
   2. Update inventory prices.
   3. Display inventory report.
3. If customer,
   1. Display account information.
   2. Add money to account.
   3. Retrieve a shopping list file.
   4. Retrieve a saved cart.
   5. Update cart contents.
   6. Display cart report.
   7. Process the cart (checkout)
