Question

Hi! I was wondering if someone can help me with my assignment! I have to create series of classes (with appropriate methods) to manage a small coffee shop. Classes should cover every business entity that would be necessary for the store, including (but not limited to):

-Inventory
-Sales
- Loyalty Cards and Promotions

-Employees (adding employees to system, hourly wages and over time, schedules, time cards, etc.)

-Finances (revenues, expenses, balance, etc)

All classes should have at least a null constructor and copy constructor. Other constructors would be up to your discretion. Include all necessary accessors and modifiers. Your group will determine the utility functions for each class.

To test your classes, create a Container class with simply a main() method. The Container class will have attributes that are class objects of each of the classes you create. The main() method will create the class objects, perform some normal business for that store, and produce appropriate output, like:

-Changes to inventory
-Daily profit
-Any other output appropriate to your chosen business

I would really appreciate any help!! Thank you so much!!:)
