Safe switch

A Better Enum can be used directly in a switch statement:

#include <iostream>
<em>#include <enum.h></em>

<em>ENUM(Channel, int, Red, Green, Blue)</em>

int main()
{
    Channel     channel = Channel::Green;
    int         n;

    <em>switch </em>(<em>channel</em>) {
        <em>case Channel::Red</em>:   n = 13; break;
        <em>case Channel::Green</em>: n = 37; break;
        <em>case Channel::Blue</em>:  n = 42; break;
    }

If you miss a case or add a redundant one, your compiler should be able to give you a warning — try it!

    std::cout << n << std::endl;
    return 0;
}
