Internet Service Provider

An Internet service provider has three different subscription packages for its customers:

Package A: $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour.

Package B: $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour.

Package C: $19.95 per month unlimited access is provided.

Write a program (c++) that calculates a customer’s monthly bill. It should ask which package the customer has purchased and how many hours were used. It should then display the total amount due. Input Validation: Be sure the user only selects package A, B, or C. Also, the number of hours used in a month cannot exceed 744. Exit the program if user enters incorrect information.

Internet Service Provider, Part 2

Modify the program (Don’t forget to save the first version for submission!) for Internet Service Provider Part 1 so that it also displays how much money Package A customers would save if they purchased packages B or C, and how much money Package B customers would save if they purchased Package C. If there would be no savings, no message should be printed.
