Design a program to calculate awards points for a book club. The club awards points to its customers based on the number of books purposed per month. The points are awareded as follows:

If a customer purposes 0 books, he/she earns 0 point.

If a customer purposes 1 books, he/she earns 5 points.

If a customer purposes 2 books, he/she earns 15 points.

If a customer purposes 3 books, he/she earns 30 points.

If a customer purposes 4 or more books, he/she earns 60 points. (Notes: The processing function may need two parameters, and returns points earned. Please use multiple-alternative decison structure. DO NOT use separate single-alternative if sets.)
