C++ question

5.10 Program: Painting a wall (C++)

(1) Prompt the user to input a wall's height and width. Calculate and output the wall's area. (Submit for 2 points).

Enter wall height (feet): 12
Enter wall width (feet): 15
Wall area: 180 square feet

(2) Extend to also calculate and output the amount of paint in gallons needed to paint the wall. Assume a gallon of paint covers 350 square feet. Store this value using a const double variable. (Submit for 2 points, so 4 points total).

Enter wall height (feet): 12
Enter wall width (feet): 15
Wall area: 180 square feet
Paint needed: 0.514286 gallons

(3) Extend to also calculate and output the number of 1 gallon cans needed to paint the wall. Hint: Use a math function to round up to the nearest gallon. (Submit for 2 points, so 6 points total).

Enter wall height (feet): 12
Enter wall width (feet): 15
Wall area: 180 square feet
Paint needed: 0.514286 gallons
Cans needed: 1 can(s)

 

 

 

#include <iostream>
#include <cmath> // Note: Needed for math functions in part (3) using namespace std; int main() {
double wallHeight = 0.0;
double wallWidth = 0.0;
double wallArea = 0.0; cout << "Enter wall height (feet): ";
cin >> wallHeight;
cout << endl; wallWidth = 10.0; // FIXME (1): Prompt user to input wall's width // Calculate and output wall area
wallArea = 0.0; // FIXME (1): Calculate the wall's area cout << "Wall area: " << endl; // FIXME (1): Finish the output statement // FIXME (2): Calculate and output the amount of paint in gallons needed to paint the wall // FIXME (3): Calculate and output the number of 1 gallon cans needed to paint the wall, rounded up to
nearest integer return 0;
}
