4. Classes & objects :
Classes contain data members, which is also
known as attributes and the member

Objects are the instances of the class or
entities through which class is
implemented in the real world.

6. Creating Daughter or Derived classes

functions of base class.

Inheritance :

7. Polymorphism :
In C++ Polymorphism means
that a call to a member function in
base class, will cause a different
function in derived to be executed
depending on the type of object that
invokes the function.

8. Encapsulation :
Encapsulation is a process of combining data
members and functions in a single unit called class.
This is to prevent the access to the data directly, the
access to them is provided through the functions of
the class.
It is one of the popular feature of Object Oriented
Programming(OOPs) that helps in data hiding.
