Once
dynamic binding is enabled, an overridden member
|
|
|
function
is bound to a pointer or reference based on the
|
|
|
type
of the object pointed to.
|
|
|
| • |
Dynamic
binding is not in effect if an object is used
|
|
|
instead
of a pointer or reference to an object.
|
|
|
| • |
Dynamic
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(); ).

For
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;
