Posible implementación

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

Ejemplo

#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
