switch statement

#include <iostream>
int main()
{
    std::cout << "Do you want to proceed (y or n)?\n";
    char answer = 0;
    std::cin >> answer; // get answer from user

    switch ( answer ) {
    case 'y':
        return true;

    case 'n':
        return false;

    default:
        std::cout << "Sorry, I don't understand\n";
        std::cout << "I'll take that for a no";
        return false;
    }
}

• default is optional
