Using std::list like this is very inefficient;

You'd be better off using a std::vector.

Vector is the simplest of the STL container classes, and in many cases the most efficient.

<code>std::ifstream file (filename);
std::vector<char> vectorStore(std::istream_iterator<char>(file), std::istream_iterator<char>());
{or}
</code><code>std::list<char> listStore(std::istream_iterator<char>(file), std::istream_iterator<char>());</code>

      std::vector<char> fileContents;
      struct _stat stat;
      if (_stat(filename, &stat) == -1) throw std::runtime_error("Can\'t open " + file);
      fileContents.resize(stat.st_size);
      std::ifstream file(filename);
      std::copy(std::istream_iterator<char>(file), std::istream_iterator<char>(),
                fileContents.begin());

strictly, you should be using unsigned chars,

In the example above you mention the N of bitset is 12. How about if you don't know the 'N'?
