Please help! I need help figuring out:(

Project 2 is a continuation of Project 1. Convert Project 1 into a menu-controlled program. Add validation for the number of minutes so numbers less than 0 are not accepted. Add functionality to process a data file containing multiple records.


Add a menu to offer the user a choice of creating a single telephone bill with payment processing or creating multiple telephone bills (without payment processing) from a data file. Add an option to quit the program. The menu should be the first thing displayed when your program begins executing. The menu format should match the one in the Sample Output.

Allow the user to continue making menu choices until they choose the option to quit. Always display the menu before prompting the user for a menu option. Properly handle an invalid menu choice. The user should have an unlimited number of chances to enter a valid menu choice.

Validate the user’s input for payment amount to allow user an unlimited number of chances to enter a valid payment amount.

Add functionality to create and display telephone bills by reading input from the TelephoneData.txt text file. When the user selects the option to create multiple telephone bills, bills should be calculated and displayed for every record in the file without the user needing to do anything else. The TelephoneData .txt file contains 5 records, but your program must be able to process an identically formatted file with any number of records without counting the records. You do not need to process payment information if this option is chosen by the user.

Save your .cpp file using the required naming format.

You might want to put your code in code format for better clarification.

Hello blackwaterdad,

PLEASE ALWAYS USE CODE TAGS (the <> formatting button), to the right of this box, when posting code.

It makes it easier to read your code and also easier to respond to your post.

http://www.cplusplus.com/articles/jEywvCM9/
http://www.cplusplus.com/articles/z13hAqkS/

Hint: You can edit your post, highlight your code and press the <> formatting button.
You can use the preview button at the bottom to see how it looks.

I found the second link to be the most help.

Right now your program looks like it might work. I will have to dig into it tomorrow.

After two years of working with menus I have found it is better to put the menu in a function surrounded by a do/while loop allowing you to make a choice and validate that choice before returning a valid choice to the calling function. Where I use a switch to process the menu choice.

You might want to consider putting most of what is in "main" in a do/while loop to keep the program continuing until the exit is called for.

I would also consider putting the input in a function and the "Display the bill" section in a function just leaving "main" to control what is done.

Hope that helps,

Andy
