NAME

operator&,|,^(std::bitset) - operator&,|,^(std::bitset)

Synopsis

template< std::size_t N > (1)
bitset<N> operator&( const bitset<N>& lhs, const bitset<N>& rhs );
template< std::size_t N > (2)
bitset<N> operator|( const bitset<N>& lhs, const bitset<N>& rhs );
template< std::size_t N > (3)
bitset<N> operator^( const bitset<N>& lhs, const bitset<N>& rhs );

Performs binary AND, OR, and XOR between two bitsets, lhs and rhs.
1) Returns a bitset<N> containing the result of binary AND on corresponding pairs of bits of lhs and rhs.
2) Returns a bitset<N> containing the result of binary OR on corresponding pairs of bits of lhs and rhs.
3) Returns a bitset<N> containing the result of binary XOR on corresponding pairs of bits of lhs and rhs.

Parameters

lhs - the bitset on the left-hand side of the operator
rhs - the bitset on the right-hand side of the operator

Return value

1) bitset<N>(lhs) &= rhs
2) bitset<N>(lhs) |= rhs
3) bitset<N>(lhs) ^= rhs

Exceptions

Example

// Run this code

  #include <bitset>
  #include <iostream>

  int main()
  {
      std::bitset<4> b1("0110");
      std::bitset<4> b2("0011");
      std::cout << "b1 & b2: " << (b1 & b2) << '\n';
      std::cout << "b1 | b2: " << (b1 | b2) << '\n';
      std::cout << "b1 ^ b2: " << (b1 ^ b2) << '\n';
  }

Output:

  b1 & b2: 0010
  b1 | b2: 0111
  b1 ^ b2: 0101
