(C++) Using VOID FUNCTIONSPlan and code a program utilizing one file for input, one file for output and one file for errors 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 error data to a separate error file.
