5. Polymorphism
1. A derived class object contains all the base class data.
2. Inheritance cannot suppress the base class functionality.
3. A derived class may not be able to access all the base class data.
4. Inheritance cannot extend the base class functionality.
5. In inheritance chain construction of object happens from base towards derived.
