template<size_t N> constexpr bitset<N> operator&(const bitset<N>& lhs, const bitset<N>& rhs) noexcept;

Returns: bitset<N>(lhs) &= rhs.

template<size_t N> constexpr bitset<N> operator|(const bitset<N>& lhs, const bitset<N>& rhs) noexcept;

Returns: bitset<N>(lhs) |= rhs.

template<size_t N> constexpr bitset<N> operator^(const bitset<N>& lhs, const bitset<N>& rhs) noexcept;

Returns: bitset<N>(lhs) ^= rhs.

template<class charT, class traits, size_t N> basic_istream<charT, traits>& operator>>(basic_istream<charT, traits>& is, bitset<N>& x);

Effects: Extracts up to N characters from is.

Stores these characters in a temporary object str of typebasic_string<charT, traits>, then evaluates the expressionx = bitset<N>(str).

Characters are extracted and stored until any of the following occurs:

• N characters have been extracted and stored;
• end-of-file occurs on the input sequence;
• the next input character is neitheris.widen('0')noris.widen('1')(in which case the input character is not extracted).

If N > 0 and no characters are stored in str,ios_base​::​failbit is set in the input function's local error state before setstate is called.

template<class charT, class traits, size_t N> basic_ostream<charT, traits>& operator<<(basic_ostream<charT, traits>& os, const bitset<N>& x);

Returns: os << x.template to_string<charT, traits, allocator<charT>>( use_facet<ctype<charT>>(os.getloc()).widen('0'), use_facet<ctype<charT>>(os.getloc()).widen('1')) (see [ostream.formatted]).
