Help Pleasse! Beginning C++ program (can't debug)
Objectives
To learn to code, compile and run a program containing three or more functions. This is a catering company.
Assignment
Plan and code a program utilizing one file for input and one file for output to solve the following problem:
A. For adults, the deluxe meals will cost $25.80 per person and the standard meals will cost $21.75 per person, dessert included. Children's meals will cost 60 percent of adult meals. Everyone within a given party must be served the same meal type.
B. All customers will be charged the same rate for tip and tax, currently 18 percent (applied only to the cost of the food).
C. A surcharge, currently 7 percent, is added to the total bill if the catering is to be done on the weekend (Friday, Saturday, or Sunday).
D. To induce customers to pay promptly, a discount is offered if payment is made within ten days.
E. This discount depends on the amount of the total bill. If the bill is less than $100.00, the discount is 1.5 percent; if the bill is at least $100.00 but less than $400.00, the discount is 2.5 percent; if the bill is $400.00 or more, the discount is 3.5 percent.
Input
Number of adults, number of children, meal type (D, S) character indicating whether or not date is a weekend (Y/N), amount of any deposit. Create the data file below in text editor or Notepad.
Output
Output an itemized bill listing the number of adults, children, cost for adult meals, cost for children's meals, total food cost, surcharge (if appropriate), tax and tip, total cost of the party, deposit (if any), total balance due, amount of discount if bill is paid within ten days. Output error data to a separate error file.
It does what it asks but my teacher said it doesn't work. I think the problems is my functions but I don't know how to fix it since I don't know the problem. Help please.

Well in order to be able to provide some guidance, you'll need to post your code so that we can have a look at it.
When posting code, please use code tags. Go Advanced, select the pasted formatted code and click '#'.

In an educational situation "working" may not be good enougth. Maybe the code should be of a certain quality reflecting what you have been taught.
Why not ask the teacher to be more specific about what's the problem with your effort.
Re: Help Pleasse! Beginning C++ program (can't debug)
So this is what I've written so far. And thanks i didn't know how to do this so i made an attachment the first time.
So it works fine until it get to the errors which it does send to the error file but then it doesn't actually do the ones that are correct. Therefore i think the Booleans aren't resetting but i don't know how to make them reset after each row.

The program either works and produces the correct output from the given input - or it does not. If the output produced is not correct as expected then the program does not work and has a fault - which you will need to investigate and correct. If the program does produce the expected output then it 'works' and the teacher cannot say that it doesn't. The teacher may be critical of your program design and code but cannot say it doesn't work if the output is correct.
You need to establish the issue. Either the program does not work or it does and the design/code is being criticised.
