Question

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

Try the following: using System; class Program { static void Main() { double total = 0; int product; int quantity; double price = 0; while(true) { do { Console.Write(Enter product number (1-5) or 0 to quit : ); int.TryParse(Console.ReadLine() out product); if (product 5) { Console.WriteLine(Not a valid product number try again); } } while(product 5); if (product == 0) break; do { Console.Write(Enter quantity sold or 0 to quit : ); int.TryParse(Console.ReadLine() out quantity); if (quantity { Console.WriteLine(Not a valid quantity sold try again); } } while(quantity if(quantity == 0) break; switch(product) { case 1: price = 2.98; break; case 2: price = 4.50; break; case 3: price = 9.98; break; case 4: price = 4.49; break; case 5: price = 6.87; break; } total += price * quantity; Console.WriteLine(); } Console.WriteLine(
The total retail value of all products sold is ${0:F2} total); Console.ReadKey(); } }
