std::hash (C++11)

 

std::size_t size() const;		(until C++11)
constexpr std::size_t size() const noexcept;		(since C++11)

Returns the number of bits that the bitset can hold.

Parameters

(none)

Return value

number of bits that the bitset can hold, i.e. the template parameter N

count

returns the number of bits set to true (public member function)
