Assignment

Plan and code a program utilizing one file for input and one file for output to solve the following problem: Write a complete program to calculate painting costs for customers of Top Quality Home Painting Service.

Function $1$: Input

Input data from a file. One record of data contains the following sequence of data:

ABC $1234,400,3\mathrm{.}50,850,5\mathrm{.}50$

$3$ customer initials, customer account number $(4$ digit integer$),$ the number of interior square feet to be painted, the cost per square foot for interior painting, the number of exterior square feet to be painted, the cost per square foot for exterior painting. Validate that no input is negative. If any data record contains an error, output the data to an error file with a message indicating what caused the error and do not produce a bill.

Function $2$: Calculate. Determine the cost for interior painting, the cost for exterior painting, and the cost for the entire paint job. Any painting estimate greater than $$1000\mathrm{.}00$ receives a $10\%$ discount.

Function $3$: Output all data $($customer initials, customer account number, interior square feet, cost per interior square feet, exterior square feet, cost per exterior square feet, total interior cost, total exterior cost, any discount and total cost$)$ to an output file..

Create the data file below using your text editor or Notepad.
