Question

C++, please make it as simple as possible.

A Paint Company is hiring you to develop an application to estimate the costs for a job. They have determined that for every 120 square feet of wall area, one gallon of paint and eight hours of labor is required. The company charges US$ 18.00 per hour for labor. Write a modular program that allows the user to enter the number of rooms that are to be painted and the price of the paint per gallon. It should also ask the user for the square feet of wall in each room. It should then display the following information: - - - - The number of gallons of paint required. The hours of labor required. The cost of the paint. The cost of the labor. 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 US$ 10.00 for the price of the gallon of paint. Do not accept a non-positive value for the square footage of wall area. You should create a function to calculate the costs and print the report. It should receive as parameters the information on "Area to be Painted" and "Price of Gallon of Paint". This is the prototype of the function to be created: void estimateCostAndPrintReport(double areaToBePainted, double priceOfGallonOfPaint); 10 Example output: How many rooms will be painted? (minimum of one) Number of Rooms needs to be at least one. How many rooms will be painted? (minimum of one) Enter the price for a gallon of paint. Gallon of paint should cost at least US$10.00. Enter the price for a gallon of paint. Enter the area (sqr ft) of wall to be painted in room 1. Area to be painted needs to be positive. Enter the area (sqr ft) of wall' to be painted in room 1. 200 Enter the area (sor ft) of wall to be painted in room 2, 230 Enter the area (sar ft) of wall to be painted in room 3. 300 Number of gallons of paint required: 7., Hours of labor required = 49. Total cost of material = US$ 70.00. Total cost of labor = US$ 882.00. Total cost of painting job (material + labor) = US$ 952.00. -1

}
