C/C++ efficient bit array

Question

Can you recommend efficient/clean way to manipulate arbitrary length bit array?

Right now I am using regular int/char bitmask, but those are not very clean when arra

Answer 1

I have recently released BITSCAN, a C++ bit string library which is specifically oriented towards fast bit scanning operations. BITSCAN is available here. It is in alpha but still pretty well tested since I have used it in recent years for research in combinatorial optimization (e.g. in BBMC, a state of the art exact maximum clique algorithm). A comparison with other well known C++ implementations (STL or BOOST) may be found here.

I hope you find it useful. Any feedback is welcome.
