Ask user to key in the required details depending on their selected shape. The program will keep asking user for input unless the user enters 0 to exit. The following functions have to be used in the program: i. double square (double s); - this function will return perimeter of square ii. double rectangle (double 1, double w) ; - this function will return perimeter of rectangle iii. double circle (double r): - this function will return circumference of circle The following formulas are to be used to calculate the perimeter of a square, a triangle and the circumference of a circle: Perimeter of a square = 4s where s is the side of the square. Perimeter of a rectange = a +b +cwhere a, b and c are the sides of the rectangle. Circumference of a circle = 2 mr where…arrow_forwardWhat will be the value of AL after executing the following code?

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.arrow_forward
