CIS210 Introduction to C Programming Fall 2016 AssignmentX P

CIS-210 Introduction to C++ Programming (Fall 2016) Assignment-X Points: 100 Due Date: 10/26/2016 (before class) Specifications: The Fairhope Utility Company charges subscribers for their electricity consumption according to the following table (monthly rates) 1. Kilowatt-hours 0 s kwh s 400 5per kwh $0.08 401 5 kWhs 1500 $0.15 1501 s kwh 3500 | 24 3501 s kWh 29 Note: Distribution charges a well as federal state and local taxes add 10%to each bill. Write a C++ program that reads the customer names, account number, and kWh consumed from a text file called electric_usage.txt and then outputs to the file, bill info.txt, the customer name, account number and total amount to pay. See sample input / output below . 2. Sample Input/Output electrical usage.txt (input) Tom 123-49-82 2100 Mark 241-87-11 346 Nancy 198-85-07 5002 Beth 342-53-49 2812 Erin 787-63-88 688 brmat the outpat wes bvo decma ives two decmal places bill info.txt (output) Fo Customer Name: Tom Account Number: 123-49-82 Bill Amount: 554.40 Customer Name: Mark Account Number: 241-87-11 Bill Amount: 30.45

Solution
