Programming Logic and Design, Introductory 7th Edition by Joyce Farrell

Exercise 15

a. Draw a flowchart or write pseudocode to represent the logic of a program that allows the user to enter values for the width and length of a wall in feet. The program outputs the area of the wall in square feet.

b. Modify the program that computes wall area to allow the user to enter the price of a gallon of paint. Assume that a gallon of paint covers 350 square feet of a wall. The program outputs the number of gallons needed and the cost of the job. (For this exercise, assume that you do not need to account for windows or doors, and that you can purchase partial gallons of paint.)
