Complete FIXME1: add an overloaded function volume that calculates the volume of a pyramid.

Area of the base = length times width

Volume of a pyramid = ? area of base times height

Length and width are ints

Height is a double

Parameters should be in the order length, width, height.

Compile your program and check for errors.

Complete FIXME2: Update processChoice function to handle case 4 (the case to calculate the volume of a pyramid) using the function you just added.

Here is my code:

#include #include #include #include #include #include using namespace std;

const double pi = 3.14;

// Volume of a sphere: 4/3 pi r^3 double volume(double r) // r is radius { return pi * r * r * r * 4 / 3; }

// Volume of a cube: a^3 double volume(int a) // a is length of side { return a * a * a; }

// Volume of a cylinder: (pi r^2) * h [area of circle times height] double volume(double r, int h) // r is radius, h is height { return pi * r * r * h; }

// FIXME 1 // Volume of a pyramid: 1/3 (l * w) * h [1/3 area of base times height] // length and width should be ints, height should be a double

int getRange(int maxVal, int minVal, string prompt) { int val = 0; cout << prompt; cin >> val; if (!cin.good()) { cin.clear(); cin.ignore(numeric_limits::max(), ' '); throw runtime_error("Invalid input. Expected a number."); } return val; }

// FIXME 2: Update the function to handle case 4. void processChoice(int choice) { double startTemp = 0; double endTemp = 0; try { double vol = -1.0; // volumes are always positive, so initialize to non-valid value double r = 0; // radius int s; // side int h; // height

switch (choice) { case 1: // Sphere cout << "Enter radius: "; cin >> r; cout << "Sphere volume: " << volume(r) << endl; break; case 2: // Cube cout << "Enter length of side: "; cin >> s; cout << "Cube volume: " << volume(s) << endl; break; case 3: // Cylinder cout << "Enter radius and height: "; cin >> r >> h; cout << "Cylinder volume: " << volume(r, h) << endl; break; case 5: // do nothing we are exiting break; default: throw runtime_error("Invalid Choice: " + to_string(choice)); } } catch (char c) { ostringstream oss; oss << "Error: '" << c << "' not implemented."; throw runtime_error(oss.str()); } }

void printMenu() { cout << endl << "Menu" << endl; cout << "1: Volume of a sphere" << endl; cout << "2: Volume of a cube" << endl; cout << "3: Volume of a cylinder" << endl; cout << "4: Volume of a pyramid" << endl; cout << "5: Exit" << endl << endl; }

int main() { int minVal = 1; int maxVal = 5; cout << "Volume Calculator:" << endl; int choice = 0; while (choice != maxVal) { try { printMenu(); choice = getRange(minVal, maxVal, "Enter choice: "); processChoice(choice); } catch (runtime_error& e) { cout << endl << e.what() << endl; } } }
