NAME

operator==,!=(std::bitset) - operator==,!=(std::bitset)

Synopsis


bool operator==( const bitset<N>& rhs ) const; (1)
bool operator!=( const bitset<N>& rhs ) const; (2)


1) Returns true if all of the bits in *this and rhs are equal.
2) Returns true if any of the bits in *this and rhs are not equal.

Parameters


rhs - bitset to compare

Return value


1) true if the value of each bit in *this equals the value of the corresponding bit in rhs, otherwise false
2) true if !(*this == rhs), otherwise false

Example


Compare two bitsets to determine if they are identical:
// Run this code


  #include <iostream>
  #include <bitset>


  int main()
  {
      std::bitset<4> b1(3); // [0,0,1,1]
      std::bitset<4> b2(b1);
      std::bitset<4> b3(4); // [0,1,0,0]


      std::cout << "b1 == b2: " << (b1 == b2) << '\n';
      std::cout << "b1 == b3: " << (b1 == b3) << '\n';
      std::cout << "b1 != b3: " << (b1 != b3) << '\n';
  }

Output:


  b1 == b2: 1
  b1 == b3: 0
  b1 != b3: 1
