C++ Mobile Service Bill) A mobile phone service provider has three different subscription packages for its customers: Package A: For $29.99 per month 900 minutes are provided. Additional minutes are $0.45 per minute. Package B: For $39.99 per month 1800 minutes are provided. Additional minutes are $0.30 per minute. Package C: For $59.99 per month unlimited minutes provided. Write a program that calculates a customer's total monthly bills. It should ask which package the customer has purchased and then ask how many minutes were used. It then displays a bill showing the base bill charges (29.99, 39.99 or 59.99), the extra charges (if any) and the total monthly bill. See the following example for the correct input and output formatting. Input validation: be sure the user only enters A or a for package , B or b for package and C or c for package. If the user inputs some other value display an error message saying "Invalid input". When you ask the user to input the number of minutes and the user enters a negative value you should display the same error message (Invalid input"). In both cases, after you display the error message your program should stop (exit). Here is a sample run: C.
