Transcription: The object Next is an iterator for the List object List. Every member function of the PhoneBook class declares its own iterator. Here, Next is constructed and is initialized to the first item in the object List. If Next were a static member, a subsequent call of lookup could continue moving through the items in the list, starting where this call of lookup leaves off.
