A retail store has a preferred customer plan where customers can earn discounts on all their purchases. The amount of a customers discount is determined by the amount of the customers cumulative purchases in the store as follows: When a preferred customer spends $500, he or she gets a 5 percent discount on all future purchases. When a preferred customer spends $1,000, he or she gets a 6 percent discount on all future purchases. When a preferred customer spends $1,500, he or she gets a 7 percent discount on all future purchases. When a preferred customer spends $2,000 or more, he or she gets a 10 percent discount on all future purchases. Design a class named PreferredCustomer , which is derived from the Customer class you created in Programming Problem 4. The PreferredCustomer class should have properties for the amount of the customers purchases and the customers discount level. Demonstrate the class in a simple application.
