A binary function object that returns true if its first operand is not equal to its second operand.

Declaration


  
#include <functional>

template< class T >
struct not_equal_to : binary_function< T, T, bool >

Interface

()

bool operator()( const T& x , const T& y ) const

Returns x != y .

Example <ospace/osstd/examples/nequal.cpp>


    #include <algorithm>
#include <functional>

int input1[ 4 ] = { 1, 7, 2, 2 };
int input2[ 4 ] = { 1, 6, 2, 3 };

void
main()
  {
  int output[ 4 ];

  transform( input1, input1 + 4, input2, output, not_equal_to< int >() );

  for ( int i = 0; i < 4; ++i )
    cout << output[ i ] << "\n";
