Defined in header <bitset>
template< std::size_t N >
class bitset;

The class template bitset represents a fixed-size sequence of N bits. Bitsets can be manipulated by standard logic operators and converted to and from strings and integers.

bitset meets the requirements of CopyConstructible and CopyAssignable.

[edit] Notes

If the size of the bitset is not known at compile time, std::vector<bool> or boost::dynamic_bitset may be used.
