nOnce dynamic binding is enabled, an overridden member function is bound to a pointer or reference based on the type of the object pointed to.
nDynamic binding is not in
effect if an object is used instead
of a pointer or reference to an object.
nDynamic binding is also
not in effect if the member function
is qualified with a class name and the scope resolution operator. In this case, the function bound to
the pointer is the member function
defined by the qualifying
class. (pa->account::statement(); )
nFor example, if we assign the student object to an account object and then invoke statement, static binding is in effect and the account function is called:
account a = smith;
