23.9 Bitsets [bitset]

23.9.4 bitset operators [bitset.operators]

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

1
#

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

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

2
#

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

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

3
#

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);

4
#

A formatted input function.

5
#

Effects: Extracts up to N characters from is. Stores these characters in a temporary object str of type basic_­string<charT, traits>, then evaluates the expression x = bitset<N>(str). Characters are extracted and stored until any of the following occurs:

  • (5.1)

    N characters have been extracted and stored;

  • (5.2)

    end-of-file occurs on the input sequence;

  • (5.3)

    the next input character is neither is.widen('0') nor is.widen('1') (in which case the input character is not extracted).

6
#

If no characters are stored in str, calls is.setstate(ios_­base​::​failbit) (which may throw ios_­base​::​failure ([iostate.flags])).

7
#

Returns: is.

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

8
#

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'))
