should not assign to the members of its base class When those members arepublic or protected, a derived constructor could assign values to its base class members inside the constructor body However, doing so would violate the interface of the base Derived classes should respect the initialization intent of their base classes by using constructors rather than assigning to these members in the body of the constructor

Like any other class, a derived class may use the synthesized copy-control members described in 13 The synthesized operations copy, assign, or destroy the base-class part of the object along with the members of the derived part The base part is copied, assigned, or destroyed by using the base class' copy constructor, assignment operator, or destructor

Whether a class needs to define the copy-control members depends entirely on the class' own direct members A base class might define its own copy control while the derived uses the synthesized versions or vice versa Classes that contain only data members of class type or built-in types other than pointers usually can use the synthesized operations No special control is required to copy, assign, or destroy such members Classes with pointer members often need to define their own copy control to manage these members Our Item_base class and its derived classes can use the synthesized versions of the copycontrol operations When a Bulk_item is copied, the (synthesized) copy constructor for
