How do you set, clear, and toggle a single bit?

Using the Standard C++ Library: std::bitset<N>.
Or the Boost version: boost::dynamic_bitset.
There is no need to roll your own:

#include <bitset>

#include <iostream>



int main()

{

    std::bitset<5> x;



    x[1] = 1;

    x[2] = 0;

    // Note x[0-4]  valid



    std::cout << x << std::endl;

}

[Alpha:] > ./a.out

The Boost version allows a runtime sized bitset compared with a standard library compile-time sized bitset.
