Defined in header <algorithm>
template<class BidirIt, class OutputIt > OutputIt reverse_copy( BidirIt first, BidirIt last, OutputIt d_first );

Copia gli elementi della [first, last) gamma, per un altro inizio montuoso a d_first in modo tale che gli elementi della nuova gamma sono in.. ordine inverso.

Original:

Copies the elements from the range [first, last), to another range beginning at d_first in such a way, that the elements in the new range are in reverse order.

Possibile implementazione

template<class BidirIt, class OutputIt> OutputIt reverse_copy(BidirIt first, BidirIt last, OutputIt d_first){while(first != last){*(d_first++)=*(--last);}return d_first;}

Esempio

#include <vector>#include <iostream>#include <algorithm>   int main(){std::vector<int> v({1,2,3});std::for_each(std::begin(v), std::end(v), [&](int value){std::cout<< value <<" ";});std::cout<<std::endl;   std::vector<int> destiny(3); std::reverse_copy(std::begin(v), std::end(v), std::begin(destiny));std::for_each(std::begin(destiny), std::end(destiny), [&](int value){std::cout<< value <<" ";});std::cout<<std::endl;}

Output:

1 2 3 3 2 1

Complessità
