nDynamic binding allows a heterogeneous collection of objects to be processed in a homogeneous way.
nThe true benefit of
dynamic binding is achieved when programs
can process different types of objects using a common interface.
nApplications use only
virtual functions defined in the base
class. The application has no knowledge about any derived class, but can generate statements appropriate for each type of account, depending on where base class pointers reference.
nIf additional types of accounts are later added to the class hierarchy, the application can easily generate statements appropriate to those accounts.
