Question
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 exist500, he or she gets a 5% discount on all future purchases. When a preferred customer spends exist1,000, he or she gets a 6% discount on all future purchases. When a preferred customer spends exist1, 500, he or she gets a 7% discount on all future purchases. When a preferred customer spends exist2,000 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 the previous problem. 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. Create a modified enterNCustomers (int n) function that asks to enter n number customers. All the customer fields must be filled in, and the result of the function is a vector containing n PreferredCustomer objects. You have the same options of text file or user input as the previous problem. Just like the previous problem, create another function that displays all the customer information to the console. Input Validation: Do not accept negative values for any sales figures.Explanation / Answer
