Design a class named PreferredCustomer, which is derived from the CustomerData class you previously created. The PreferredCustomer class should have the following member variables: · purchasesAmount ( a double) · discountLevel (a double)
The purchasesAmount variable holds the total of a customer’s purchases to date. The discountLevel variable should be set to the correct discount percentage, according to the store’s preferred customer plan.
