bitset::operator==

Tests a target bitset for equality with a specified bitset.

bool operator ==( 
   const bitset<N>& _Right 
) const;

Parameters

• _Right
  The bitset that is to be compared to the target bitset for equality.

Return Value

true if the bitsets are the same; false if they are different.

Remarks

Bitsets must be of the same size to be tested for equality by the member operator function.

Example

// bitset_op_EQ.cpp
// compile with: /EHsc
#include <bitset>
#include <iostream>

int main( )
{
   using namespace std;
   bitset<5> b1 ( 7 );
   bitset<5> b2 ( 7 );
   bitset<5> b3 ( 2 );
   bitset<4> b4 ( 7 );

   if ( b1 == b2 )
      cout << "Bitset b1 is the same as bitset b2." << endl;
   else
      cout << "Bitset b1 is different from bitset b2." << endl;

   if ( b1 == b3 )
      cout << "Bitset b1 is the same as bitset b3." << endl;
   else
      cout << "Bitset b1 is different from bitset b3." << endl;

   // This would cause an error because bitsets must have the 
   // same size to be tested
   // if ( b1 == b4 )
   //   cout << "Bitset b1 is the same as bitset b4." << endl;
   // else
   //   cout << "Bitset b1 is different from bitset b4." << endl;
}

Bitset b1 is the same as bitset b2.
Bitset b1 is different from bitset b3.
