I am trying to write a function with takes a vector of
pair and an key (integer).
it should return true if the input key matches the
FIRST value of the map.
bool containsPair(vector< pair >& aMap, int
key ) {
return ( find_if ( aMap.begin(), aMap.end(),  bind(
equal_to<int>(),  boost::lambda::bind( &pair< int,
int>::first_type::first, boost::lambda::_1) , key )  )
!=  aMap.end());
}
But i cant' get the code to compile.
Use bind( &pair::first, _1 ) == key.
