Write a multiple-alternative selection structure that determines the appropriate discount rate based on a promotion code entered by the user. The user’s entry is stored in the intPromoCode variable. The valid promotion codes are 1, 2, 3, and 4. The corresponding discount rates are 2%, 5%, 10%, and 25%, respectively. Assign the discount rate (converted to decimal) to the decRate variable. If the user enters an invalid promotion code, assign the number 0 to the decRate variable. Use the If/ElseIf/Else form of the If... Then...Else statement.

- 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.arrow_forwardQ7: When a user is asked to input one digit, how can you test to make sure that a user entered only one?
