I really need help for this program on C$++.$ I have no clue what to do$.$ I can't use arrays and structures for this lab. I also need to have an input file, an error file, and a output file

Objectives$--$To learn to code, compile and run a program containing functions for a catering company.

Assignment$$phase $1$

The problem$--$ A catering company needs to calculate the charges for parties they are going to work on$.$

Function $1$: Create a function to input data from a file. See sample data below. Validate the data$$meal type must be S

or D$,$ Weekend must be Y or N$,$ deposit cannot be negative. Output errors with appropriate messages to an error file.

Test this module.

Function $2$: Calculate cost of the meals for adults and children. For adults, the deluxe meals will cost $$25\mathrm{.}80$ per person

and the standard meals will cost $$21\mathrm{.}75$ per person. Children's meals will cost $60$ percent of adult meals. Everyone

within a given party must be served the same meal type. Return the total cost of the meals.

Function $3$: Calculate additional costs. Calculate tip and tax. All customers will be charged the same rate for tip and tax,

$($currently $18$ percent applied only to the cost of the food$).$ Calculate surcharge, currently $7$ percent, which is added to

the total bill if the catering is to be done on the weekend $($Friday$,$ Saturday, or Sunday$).$ Return the tip$/$tax and the

surcharge.

Function $4$: Calculate total bill and output data to the screen. Output: an itemized bill listing the party ID$,$ number of

adults, children, cost for meals, surcharge $($if appropriate$),$ tax and tip, total cost of the party, deposit $($if any$),$ total

balance due.

Input

Party ID $,$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.

Data File

$1100$ S Y $100\mathrm{.}00$

$2273$ D Y $57\mathrm{.}50$

$312517$ D N $0\mathrm{.}00$

$440$ S N $25\mathrm{.}00$

$5025$ S Y $23\mathrm{.}75$

$625043$ D N $500\mathrm{.}00$

$700$ D N $0\mathrm{.}0$

$8100$ R Y $10\mathrm{.}00$

$9173$ D R $15\mathrm{.}00$

$1050$ D Y $275\mathrm{.}00$

$11-310$ D Y $20\mathrm{.}00$

$1214-1$ S N $30\mathrm{.}00$

$13203$ D Y $-10\mathrm{.}00$

Output: Screen output showing party ID$,$ Number of adults, number of Children,Meal type, total meal cost, tax$/$tip$,$

surcharge, total party cost. Errors show on error file with type of error specified.

To hand in: The structure chart, the program listing, and the output.
