Mobile Service Provider

A mobile phone service provider has three different data plans for its customers: Package A: For $39.99 per month, 4 gigabytes are provided. Additional data costs $10 per gigabyte. Package B: For $59.99 per month, 8 gigabytes are provided. Additional data costs $5 per gigabyte. Package C: For $69.99 per month, unlimited data is provided. Write a program that calculates a customer's monthly bill. It should ask which package the customer has purchased and how many gigabytes were used. It should then display the total amount due. Input Validation: Be sure the user only selects package A, B, or C.

use the included .cpp file and add it your solution file. Include the following modifications. Declare constants to store base prices for packages. For example, 39.99 for Package A, 59.99 for Package B, and 69.99 for Package C. Make sure the customer name and billing month is accepted. Billing month should be in the range 1-12. If it is not, please display an error message. Make sure a user enters only 'A', 'B' or 'C' for the plan package code. Display an error message if any other letter is entered. Only if a valid package code ('A','B', or 'C') is entered, then the user should be asked to enter the number of gigabytes used Display a bill with month of bill, customer name, package code, charges included in package deal, and charge for additional data. Make sure you use identifying labels too.
