Template below:

include <iostream>
#include <cmath> // Note: Needed for math functions in part (3)
#include <iomanip> // For setprecision
using namespace std;

int main() {
double wallHeight;
double wallWidth;
double wallArea;

cout << "Enter wall height (feet):" << endl;
cin >> wallHeight;

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;
}

Output each floating-point value with two digits after the decimal point, which can be achieved by executing
cout << fixed << setprecision(2); once before all other cout statements.
(1) Prompt the user to input a wall's height and width. Calculate and output the wall's area. (2 pts)
Note: This zyLab outputs a newline after each user-input prompt. For convenience in the examples below, the user's input
value is shown on the next line, but such values don't actually appear as output when the program runs.
Enter wall height (feet):
12.0
Enter wall width (feet):
15.0
Wall
area:
180.00 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. (2 pts)
Enter wall height (feet):
12.0
Enter wall width (feet):
15.0
Wall area: 180.00 square feet
Paint needed: 0.51 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. (2 pts)
Enter wall height (feet):
12.0
Enter wall width (feet):
15.0
Wall area:
180.00 square feet
Paint needed: 0.51 gallons
Cans needed: 1 can(s)
