Question

A painting company has determined that for every 110 square feet of wall space, one gallon of paint and eight hours of labor will be required. The company charges $25.00 per hour for labor. Write a modular program that allows the user to enter the number of rooms that are to be painted (different colors) and the price of the paint per gallon. It should also ask for the square feet of wall space in each room. Rooms and gallons are whole-numbers only. It should then display the following data:
The number of gallons of paint required
The hours of labor required
The cost of the paint
The labor charges
The total cost of the paint job
Input validation: Do not accept a value less than 1 for the number of rooms. Do not accept a value less than $10.00 for the price of paint. Do not accept a negative value for square footage of wall space.
Use the following string literals:
"Room " ": "
"Enter the number of rooms to be painted: "
"ERROR: Enter 1 or greater.\n"
"Enter the number of rooms to be painted: "
"Enter the price of the paint, per gallon: "
"ERROR: Paint price must be 10.00 or greater.\n"
"Enter the price of the paint, per gallon: "
"Enter the area of wall space in square feet: "
"ERROR: Wall area must be a non-negative number.\n"
"Enter the area of wall space in square feet: "
"\nESTIMATED CHARGES\n"
"------------------\n"
"Gallons of paint: "
"Price per gallon: $"
"Paint cost: $"
"Hours of labor: "
"Total charges: $"

Using the following test data:
2, 39.95, 112, 80

Your output should look like this:
Enter the number of rooms to be painted: 2    Enter the price of the paint, per gallon: 39.95 Room 1: Enter the area of wall space in square feet: 112 Room 2:    Enter the area of wall space in square feet: 80   
ESTIMATED CHARGES
------------------
Gallons of paint: 2
Price per gallon: $39.95
Paint cost: $79.90
Hours of labor: 13.96
Total charges: $428.99

This is c++ and please let the code works on VS2017.

please show the output same as the output I gave you. Thank you.
