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 in C++ 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 of 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.)
