Elemento definito nell'header <memory>
template<class InputIt, class ForwardIt > ForwardIt uninitialized_copy( InputIt first, InputIt last, ForwardIt d_first );

Copia elementi del [first, last) gamma ad un inizio di memoria non inizializzata zona a d_first. Gli elementi della zona non inizializzata sono costruiti utilizzando il costruttore di copia.

Original:

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.
