PreferredCustomer Class
A retail store has a preferred customer plan where customers may earn discounts on all their purchases. The amount of a customer’s discount is determined by the amount of the customer’s cumulative purchases in the store.
• When a preferred customer spends $500, he or she gets a 5% discount on all future purchases.
• When a preferred customer spends $1,000, he or she gets a 6% discount on all future purchases.
• When a preferred customer spends $1,500, he or she gets a 7% discount on all future purchases.
• When a preferred customer spends $2,000 or more, he or she gets a 10% discount on all future purchases.
Design a class named PreferredCustomer, which is derived from the CustomerData class you created in Programming Challenge 7. 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. Write appropriate member functions for this class and demonstrate it in a simple program.
