Problem is in C++ Write a program that computes the phone bills for a list of customers from a file. Write a report of the bill to an output file. Your bill is based on the number of hours of phone use, along with your package. Here are the different packages: -------------------------------------------------------------------------- Basic package: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour. Gold package: For $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour. Platinum package: For $19.95 per month unlimited access is provided. -------------------------------------------------------------------------- Write a program that reads from a file called "customers.txt". The first line of the file will be a number stating how many customers are listed in the file. Each subsequent line will consist of a name, followed by a package type, followed by a number of phone hours used by that customer. Here is an example: 5 Schweller gold 19 Garret platinum 59 Kolter platinum 12 Schwarzeneger basic 237 Hansen gold 23 As output, write to a file billing.txt a list of each customer followed by their total bill for the month. For the above file, the corresponding output file should contain: Schweller $14.95 Garret $19.95 Kolter $19.95 Schwarzeneger $463.95 Hansen $17.95
