Need Program Output for a health card menu

Hi
I need to write a program. It’s very much difficult for me to attempt without any help. Please give me an idea solution to understand how can i solve this program?
This is about to write a program that will display the following menu of a health club:
- Standard Adult Membership
- Child Membership
- Senior Citizen Membership
- Quit the program
The program will take input from the user about the choice selection of above menu and also will take number of months. Then the program will calculate the membership charges for the given number of months as follows:
- Standard Adult Membership Rs.50
- Child Membership Rs.20
- Senior Citizen Membership Rs.30
