A binary function object that returns true if either of its operands are true .

Declaration


  
#include <functional>

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

Interface

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

Returns ( x || y ) .

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


    #include <algorithm>
#include <functional>

bool input1[ 4 ] = { 1, 1, 0, 1 };
bool input2[ 4 ] = { 0, 1, 0, 0 };

void
main()
  {
  int output[ 4 ];

  transform( input1, input1 + 4, input2, output, logical_or< bool >() );

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