Internet Service Provider Part 1
An International Internet phone company has three different subscription packages for its
customers:
Package A: For $9.95 per month 5 hours of call time are provided. Additional
usage costs $0.08 per minute.
Package B: For $14.95 per month 10 hours of call time are provided. Additional
usage costs $0.06 per minute.
Package C: For $19.95 per month unlimited call time is provided.
Write a program that calculates a customer’s monthly bill. It should input customer name,
which package the customer has purchased, and how many hours were used. It should
then create a bill that includes the input information and the total amount due. Wherever
possible use named constants instead of numbers.
Input Validation: Be sure the user only selects package A, B, or C.
