The cost to become a member of a fitness center is as follows: 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 menu-driven 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. Use appropriate parameters to pass information in and out of a function. (Do not use any global variables.)
