Copy map values to vector in STL [duplicate]

by

You could probably use std::transform for that purpose. I would maybe prefer Neils version though, depending on what is more readable.

Example by xtofl (see comments):

#include <map>
#include <vector>
#include <algorithm>
#include <iostream>

template< typename tPair >
struct second_t {
    typename tPair::second_type operator()( const tPair& p ) const { return p.second; }
};

template< typename tMap > 
second_t< typename tMap::value_type > second( const tMap& m ) { return second_t< typename tMap::value_type >(); }


int main() {
    std::map<int,bool> m;
    m[0]=true;
    m[1]=false;
    //...
    std::vector<bool> v;
    std::transform( m.begin(), m.end(), std::back_inserter( v ), second(m) );
    std::transform( m.begin(), m.end(), std::ostream_iterator<bool>( std::cout, ";" ), second(m) );
}

Very generic, remember to give him credit if you find it useful.
