std::bitset<N>::operator&=,|=,^=,~: std::bitset<N>::operator&amp;=,|=,^=,~

NAME

std::bitset<N>::operator&=,|=,^=,~ - std::bitset<N>::operator&=,|=,^=,~

Synopsis

bitset<N>& operator&=( const bitset<N>& other ); (1)
bitset<N>& operator|=( const bitset<N>& other ); (2)
bitset<N>& operator^=( const bitset<N>& other ); (3)
bitset<N> operator~() const; (4)

Performs binary AND, OR, XOR and NOT.
1) Sets the bits to the result of binary AND on corresponding pairs of bits of *this and other.
2) Sets the bits to the result of binary OR on corresponding pairs of bits of *this and other.
3) Sets the bits to the result of binary XOR on corresponding pairs of bits of *this and other.
4) Returns a temporary copy of *this with all bits flipped (binary NOT).
Note that &=, |=, and ^= are only defined for bitsets of the same size N.

Parameters

other - another bitset

Return value

1-3) *this
4) bitset<N>(*this).flip()

Exceptions

(none) (until C++11)
noexcept specification: (since C++11)
noexcept

Example

// Run this code

  #include <iostream>
  #include <string>
  #include <bitset>

  int main()
  {
      std::bitset<16> dest;
      std::string pattern_str = "1001";
      std::bitset<16> pattern(pattern_str);

      for (size_t i = 0, ie = dest.size()/pattern_str.size(); i != ie; ++i) {
          dest <<= pattern_str.size();
          dest |= pattern;
      }
      std::cout << dest << '\n';
  }

Output:

  1001100110011001
