Question
For this programming assignment, you will write a program to compute and print the mobile phone bill for customers at a wireless carrier. The wireless carrier offers three service plans. The plan details are as follows: Plan A: $79.99 per month plus first 450 free peak-time minutes and unlimited data. Charges for over 450 minutes are $0.45 per minute. Plan B: $50 per month for unlimited minutes and 500 MB of data. 500 MB slowed to 2G speeds when 500 MB has been reached in one monthly billing cycle. No overage charges -just a message that indicates slower speed. Plan C: $28 per month for 500 minutes and 500 MB of data. Charges for over 500 minutes are $0.02 per minute; charges for over 500 MB of data are $0, 023 per MB. All mobile phone plans charge an additional 20% in various fees and taxes. Your program will contain three (3) user-defined functions with the following names and descriptions: read Customer Info: Reads customer data from the input file - one customer at a time. The input file (customers.txt) contains the last name, account number, plan letter, minutes used, and megabytes of data used. Compute Bills: Computes the monthly mobile phone bill based on the plan details display Bills: Prints the mobile phone bill details for each customer, including the customer's last name, account number, plan letter, minutes used, megabytes of data used, subtotal(charges without taxes and fees), and total (charges with 20% in taxes and fees). The bills (containing all customers' bills) should be printed to an output file named .txt Successful completion of this assignment includes (but is not limited to): Use of selection (Chapter 4), repetition (Chapter 5) and user-defined functions (Chapter 6) in this program Properly named .cop file Inclusion of the algorithm used to develop your program as comments within your program A program that compiles and executes properly A program that properly reads data from the input file, computes the monthly phone bills, and display the monthly bills in an output file.Explanation / Answer
