Answer Posted / arun prasad v.s
Nested Classes:
Merits:
Solves one of the problems in Multiple inheritance.
Lets say, Class MyDerived has to implement 2 interfaces IA &
IB, both interfaces having a method Init() with same
signature. If MyDerived implements both, it cannot specify 2
Init() methods with with same signature.
This limitation forces us to use nested classes, where
MyDerived shall have 2 nested classes MyA:public IA &
MyB:public IB and they each have their own implementation of
Init() method.
Demerits:
Still thinking ...:) May be code complexity ?
