For accommodation of at least 5 days, a customer gets discount of 25% on accommodation cost. There is no discount for accommodation of less than 3 days unless athe customer goes for SUP accommodation service in which case the discount would be 10%. Write a C++ program to input for each customer, name, type of accommodation paid for, and number of days required of accommodation, and to determine and output for each customer, accommodation charge, discount (if any) and net charge. Output should also include total (accumulated) net charges. Net charge is charge less discount. The program should work for any number of customers, and its execution should stop when either “XXX” is entered instead of customer name. The program should use function for determining discount.

2.  ABC deals in 3 kinds of products (X, Y and Z) and has several customers. Write a C++ program to accept for each sale, entries of customer name, type of products purchased by the customer and the number of units of each product.  Prices per unit of the products are sh 50, sh 75 and sh 92 for X, Y and Z respectively. Only purchases of product X any Y attract VAT of 18% of the purchase value. VAT increases amount paid by the customer. Discount is 10% of purchase value for value of at least sh. 10000 charge to a customer. A customer may buy one, two or three types of products. The output for each customer is amount to be paid by the customer.The program should make use of function is determining discount and should run till “X” is entered instead of customer name.
