Design a C++ program that reads a customer’s name, a purchase amount and a tax code. The tax code has been validated and will be one of the following :

0 – tax-exempt (0%) 1 – state sales tax only (3%) 2 – federal and state sales tax (5%) 3 – special sales tax (7%)

The program must then compute the sales tax and the total amount due and print the customer’s name, the purchase amount, sales tax and total amount due.
