bitset::operator!=

Tests a target bitset for inequality 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 inequality.

Return Value

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

Remarks

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

Example

// bitset_op_NE.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 different from bitset b2." << endl;
   else
      cout << "Bitset b1 is the same as bitset b2." << endl;

   if ( b1 != b3 )
      cout << "Bitset b1 is different from bitset b3." << endl;
   else
      cout << "Bitset b1 is the same as 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 different from bitset b4." << endl;
   // else
   //   cout << "Bitset b1 is the same as bitset b4." << endl;
}

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