std::uninitialized_copy

From cppreference.com

Defined in header `<memory>`

template< class InputIterator, class Size, class ForwardIterator > ForwardIterator uninitialized_copy_n( InputIterator first, Size count, ForwardIterator d_first);		(since C++11)

Copies count elements from a range beginning at first to an uninitialized memory area beginning at d_first. The elements in the uninitialized area are constructed using copy constructor.

template<class InputIterator, class Size, class ForwardIterator>
ForwardIterator uninitialized_copy_n(InputIterator first, Size count,
                                     ForwardIterator d_first)
{
    typedef typename std::iterator_traits<ForwardIterator>::value_type Value;
    for (; count > 0; ++first, ++d_first, --count) {
        ::new (static_cast<void*>(&*d_first)) Value(*first);
    }
    return d_first;
}
