template<class InIt, class OutIt>
    OutIt copy(InIt first, InIt last, OutIt x);

The template function evaluates *(x + N) = *(first + N)) once for each N in the range [0, last - first), for strictly increasing values of N beginning with the lowest value. It then returns x + N. If x and first designate regions of storage, x must not be in the range [first, last).
