template<class NoThrowForwardIterator, class T>
  void uninitialized_fill(NoThrowForwardIterator first, NoThrowForwardIterator last, const T& x);

Effects: Equivalent to: for (; first != last; ++first) ::new (voidify(*first)) typename iterator_traits<NoThrowForwardIterator>::value_type(x);

template<class NoThrowForwardIterator, class Size, class T>
  NoThrowForwardIterator uninitialized_fill_n(NoThrowForwardIterator first, Size n, const T& x);

Effects: Equivalent to: for (; n--; ++first) ::new (voidify(*first)) typename iterator_traits<NoThrowForwardIterator>::value_type(x); return first;

Effects: Equivalent to: return uninitialized_fill(counted_iterator(first, n), default_sentinel, x).base();
