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.$)$

An example of the program is shown below:

Welcome to Stay Healthy and Fit center.

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: $50$

Enter the cost of one personal training session: $10$

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: $1$

The membership cost $=$ $$80\mathrm{.}00$

Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of $2.$
