Extracted text: 1) Write a program that uses a for statement to calculate and print the product of the odd integers from 1 to 15. 2) A mail order house sells five different products whose product numbers and retail prices are: product 1- $2.98, product 2 - $4.50, product 3 - $9.98, product 4 - $4.49, product 5 - $6.87. a) Write a program that reads a series of pairs of numbers (from user). That is, each time it reads the pairs of values as follows: D product number 1i) quantity of that product sold b) Your program should use a switch statement to determine the retail price for each product. c) Your program should calculate and display the total retail value of all products sold. d) Use a sentinel-controlled while loop so user can indicate when the program should stop looping and display the final results.
