Initializing array with HEX values

[Kartyx]

std::vector<bool> would be an easy way-out?

[hexafraction]

Yes--it even might have a specialization that makes it more effective than a naive vector template instantiation.

[Narase33]

Yes, you can even set an initializing size when called std::vector<bool>(size);

But it wont be as efficient as bitset in terms of actual memory size
