Implementing Linked Lists (Implementing Iterators)

• Iterators are created by the begin and end functions of the List class.

  Iterator List::begin()
  {
     Iterator iter;
     iter.position = first;
     iter.last = last;
     return iter;
  }
  
  Iterator List::end()
  {
     Iterator iter;
     iter.position = NULL;
     iter.last = last;
     return iter;
  }
