Question

Appalachian Dact ofC Itin ution Problem Statement Design and build a program to estimate the gallons of paint needed to paint a wall and the estimated cost of the paint. Assume that one gallon of paint will cover 350 square feet of a wall, cach doorway accounts for 14 square feet, and each window accounts for 8.5 square feet. Obtain all other required information from the user. The output of your program must include the total cost to purchase the paint and the number of gallons needed. Additional output may include the square footage of the wall and allowances made. Appalachían
