std::uninitialized_copy

From cppreference.com

Defined in header `<memory>`

template< class InputIterator, class ForwardIterator > ForwardIterator uninitialized_copy( InputIterator first, InputIterator last, ForwardIterator d_first );

Copies elements from the range [first, last) to an uninitialized memory area beginning at d_first. The elements in the uninitialized area are constructed using copy constructor.

template<class InputIterator, class ForwardIterator>
ForwardIterator uninitialized_copy(InputIterator first, 
                                   InputIterator last,
                                   ForwardIterator d_first)
{
    typedef typename std::iterator_traits<ForwardIterator>::value_type Value;
    for (; first != last; ++first, ++d_first) {
        ::new (static_cast<void*>(&*d_first)) Value(*first);
    }
    return d_first;
}
