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

Types of Loop

Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.

Loops

Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.

While Loop

Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

Question

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

Program Purpose - Professional Athletes often hire other professionals to help take care of matters for them. We will group them in four categories: Lawyers, Personal Assistants, Agents, and Trainers. They all get paid a percentage of the athlete's total yearly salary. Lawyers - 10%, Personal Assistants - 3%, Agents - 7%, and Trainers - 5% . Prompt the user to enter the athlete's salary for the year (ensure that the entered value is positive). The user should then enter the name and category of each of the hired professionals. The athlete should be able to hire as many professionals in each category as he/she wants, even if it is more than he/she can afford. Based on the category, calculate the amount that each professional should be paid. After all data has been entered, print the names of each professional hired, how much each is being paid, the total amount the athlete paid, and how much the athlete has left.
