Question

C Code

The cost to become a member of a fitness center is as follows:

(a) the senior citizens discount is 30%

(b) if the membership is bought and paid for 12 or more months, the discount is 15%

(c) if more than five personal training sessions are bought and paid for, the discount on each session is 20% Write a 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 that prompts for the price per month of a membership and the cost of each personal trainer session (use pass by pointer parameters) a function that prompts for all of the necessary information to determine the cost of a membership (use pass by pointer parameters) a function to determine the membership cost (use pass by value parameters)

For Example: This program determines the cost of a new membership.

If you are a senior citizen, then the discount is 30% of the regular membership price.

If you buy membership for twelve months and pay today, the discount is 15%

If you buy and pay for 6 or more personal training session today, the discount on each session is 20%

Enter the cost of a regular membership per month: 100

Enter the cost of one personal training session: 11

Are you a senior citizen (Y|y/N|n): n

Enter the number of personal training sessions bought: 3

Enter the number of month you are paying for: 13

The membership cost = $1138.00
