Polymorphism in C++

Simple Note

From reference:

One of the key features of derived classes is that a pointer to a derived class is type-compatible with a pointer to its base class. Polymorphism is the art of taking advantage of this simple but powerful and versatile feature, that brings Object Oriented Methodologies to its full potential.

Virtual Keyword in C++

Simple Note

Use virtual keyword to define a function in a class that can be redefined in its derived class.

The only valid declaration (virtual or non-virtual) is the declaration within first level Class (first level here means the base class), redefine it in derived class will be ignored.
