inheriance and run time polymorphism

Sachin Chauhan

Hi All,

While thinking about inheritance and polymorphism (run time - overriding), I got confused about their implementation. Inheritance means use the base class methods in the same way as they are in base class. While in overriding, we can have our implementation of the base class method? Can any one please confirm it is correct?

What you are saying, Sachin, is essentially correct.

With inheritance, a derived class inherits all the members of its base class, except for its constructors and destructor (if any).

This includes virtual members.

Technically, it also includes private members even though they are not accessible from the derived class.

In the case of virtual methods or properties, the derived class can choose to either inherit them as they stand or to override them with its own implementation. However, if it overrides them the signature, return type and accessibility of the overridden method must be the same as it was in the base class.
