C++ <bitset> - operator| Function



The C++ <bitset> operator| function returns a bitset which contains the result of bitwise OR operation on given bitsets.

Syntax

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

Parameters

lhs Specify the first bitset object.
rhs Specify the second bitset object.

Return Value

Returns the bitset which contains the result of OR operation.

Exception

Never throws exceptions.

Example:

In the example below, the operator| function is used to perform bitwise OR operation on the given bitsets.

#include <iostream>
#include <bitset>
using namespace std;
 
int main (){
  bitset<4> bset1("1001");
  bitset<4> bset2("1100");

  cout<<"bset1 is: "<<bset1;
  cout<<"\nbset2 is: "<<bset2;

  //performing bitwise OR operation
  auto bset3 = bset1 | bset2;

  cout<<"\nbset1 | bset2 = "<<bset3;

  return 0;
}

The output of the above code will be:

bset1 is: 1001
bset2 is: 1100
bset1 | bset2 = 1101
