The last part of this code I need the gallon round to the nearest number, but it still shows wrong after I apply the round(), I don't know how to change it #include #include // Note: Needed for math functions in part(3) #include // For setprecision using namespace std; int main() { double wallHeight; double wallWidth; double wallArea; cout << "Enter wall height (feet):" << endl; cin >> wallHeight; // FIXME (1): Prompt user to input wall's width cout << "Enter wall width (feet):" << endl; cin >> wallWidth; // Calculate and output wall area wallArea = wallHeight * wallWidth; // FIXME (1): Calculate the wall's area cout << fixed << setprecision(2) << "Wall area: " << wallArea << " square feet" << endl; // FIXME (1): Finish the output statement // FIXME (2): Calculate and output the amount of paint in gallons needed to //paint the wall cout << fixed << setprecision(2) << "Paint needed: " << wallArea/350 << " gallons" << endl; // FIXME (1): Finish the output statement // FIXME (3): Calculate and output the number of 1 gallon cans needed to // paint the wall, rounded up to nearest integer cout << "Cans needed: " << round(wallArea/350) << "can(s)" << endl; return 0; }
