The cost to become a member of a fitness center is as follows: the membership fee per month is $50.00 the personal training session fee per session is $30.00 the senior citizens discount is 30% if the membership is bought and paid for 12 or more months, the discount is 15%; If more than five personal training sessions are bought and paid for, the discount on each session is 20%. Write a program that determines the cost of a new membership. Your program must contain a function that displays the general information about the fitness center and its charges, a function to get all the necessary information to determine the membership cost, and a function to determine the membership cost. Your program must also be a menu driven program. Given the user 2 options as follows: Calculate membership costs. quit this program.
