Chapter 4.14, Problem 4.31CP

Rewrite the following program. Use a switch statement instead of the if /else if statement.

#include <iostream> using namespace std; int main()

{

int selection;

cout << “Which formula do you want to see?\n\n”;

cout << “ 1. Area of a circle\n”;

cout << “2. Area of a rectangle\n”;

cout << “3. Area of a cylinder\n”;

cout << “4. None of them\n”;

cin >> selection; if (selection == 1)

cout << “Pi times radius squared\n”;

else if(selection == 2)

cout << “Length times width\n”;

else if(selection == 3)

cout << “Pi times radius squared times height\n”;

else if(selection == 4)

cout << “Well okay then, good bye!\n”;

else

cout << “Not good with numbers, eh?\n”;

return 0;
