Question

Write a program that computes the cost of painting and installing carpet in a
room. Assume that the room has one door, two windows, and one bookshelf. Your program must do the following:
a. Prompts the user to enter, in feet, the length, width, and height of a
room. Read the dimensions of the room.
b. Prompts the user to enter the widths and heights, in feet, of the door,
each window, and the bookshelf. Read these quantities.
c. Prompts the user to enter the cost, per square foot, of painting the
walls. Read these quantities.
d. Prompts the user to enter of cost, per square foot, of installing carpet.
Read these quantities.
