template<class E, class T, size_t N>
basic_ostream<E, T>& operator<<(basic_ostream<E, T>& os,
const bitset<N>& x);
The template function overloads operator<<
to insert a text representation of the bit sequence in os
. It effectively
executes os << x.
to_string
<E, char_traits<E>, allocator<E> >()
, then returns os
.
