CITP 4350 Assignment 4 Design a class named Person with properties for holding a person’s name, address, and telephone number. Design a class named Customer, which is derived from the Person class. The Customer class should have the variables and properties for the customer number, customer email, a spentAmount of the customer’s purchases, and a Boolean variable indicating whether the customer wishes to be on a mailing list. It also includes a function named calcAmount that calculates the spentAmount. All retail store has a preferred customer plan where customers can 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 as follows: · When a preferred customer spends $500, he or she gets a 5% discount on all future purchases. · When a preferred customer spends $1000, he or she gets a 6% discount on all future purchases. · When a preferred customer spends $1500, he or she gets an 8% discount on all future purchases. · When a preferred customer spends $2000, he or she gets a 10% discount on all future purchases. Design a class named PreferredCustomer, which is derived from the Customer class. The PreferredCustomer class should have a variable, discountLevel, with a read-only property. It alsoincludes a setDiscountLevel function that determine the discount level based on the purchases amount using switch statement and an override function, calcAmount, calculates the spentAmount with the current discount level. Create a CustomerDemo class. In the main function, the program calls the getData function to read the data from the “CustomerInfo.txt” file and create a dynamic array of PreferredCustomer object. Then, it prompts user to enter a customer number and displays a menu: 1. Display Customer Information: display the specific customer information 2. Update Spent Amount: update the total amount with the correct discount level After update the spent Amount, the program writes the updated information back to file. 5 Anna Alaniz 123 10th st, McAllen, TX 78504 956-456-7899 A0000001 [email protected] 2500 true Bob Ho 456 15th st, McAllen, TX 78504 956-456-1000 A0000002 [email protected] 2500 true Hector Alcoser 2004 44th st, McAllen, TX 78501 956-456-5555 A0000003 [email protected] 495 false Jorge Lee 123 10th st, McAllen, TX 78504 956-555-6666 A0000004 [email protected] 1200 true Pablo Gonzalez 777 2th st, McAllen, TX 78502 956-100-2000 A0000005 [email protected] 1750 false
