A mail order house sells five different
products whose retail prices are: product 1 $2.98, product 2 $4.50, product 3
$9.98, product 4 $4.49 and product 5 $6.87. Write a program that reads a series
of pairs of numbers as follows:
Product
number
Quantity
sold
Your
program should use a switch statement to determine the retail price for each product. Your
program should calculate and display the total retail value of all products
sold. Use a sentinel-controlled loop to determine when the program should stop
looping and display the final results
