• If you have implemented lists, and you wish to perform an operation on all the elements in a list, then you should define the iterator class, and you should create an iterator object by instantiating the following pattern:

  iterator<object type> iterator name (list name); 
  

• If you have implemented iterators, and you wish to work on the object pointed to by an iterator class object, and you have defined an access member function, then instantiate the following pattern:

  iterator name.access ( ) 
  

• If you have implemented iterators, and you wish to move an iterator class object's pointer to the next link in a list, and you have defined a advance member function, then instantiate the following pattern:

  iterator name.advance ( ) 
  

• If you have implemented iterators, and you wish to work on all the elements in a list, and you have created an iterator class object using a class with access, advance, endp, and reset member functions, then instantiate the following pattern:

  iterator name.reset ( ); 
  for (; iterator name.endp ( ) ; iterator name.advance ( )) { 
     ... iterator name.access ( ) ... 
  }
