Object Oriented Programming Using C++

Concept Of Object Oriented Programming
OOPs is an approach or a Programming pattern where the
programs are structured around objects rather than functions and
logic. It makes the data partitioned into two memory areas, i.e.,
data and functions, and helps make the code flexible and modular.
Object-oriented programming mainly focuses on objects that are
required to be manipulated. In OOPs, it can represent data as
objects that have attributes and functions.

Basic Object-Oriented Programming
 Object-An O Object can be defined as an entity that has a
state and behavior, or in other words, anything that exists
physically in the world is called an object. It can represent a
dog, a person, a table, etc. An object means the combination
of data and programs, which further represent an entity.
 Classes-Class can be defined as a blueprint of the object. It is
basically a collection of objects which act as building blocks.

 Abstraction- Abstraction helps in the data hiding process. It
helps in displaying the essential features without showing the
details or the functionality to the user. It avoids unnecessary
information or irrelevant details and shows only that specific
part which the user wants to see.
ABSTRACTION

 Encapsulation- The wrapping up of data and functions together
in a single unit is known as encapsulation. It can be achieved by
making the data members' scope private and the member
function’s scope public to access these data members.
Encapsulation makes the data non-accessible to the outside
world.
ENCAPSULATION

 Inheritance- Inheritance is the process in which two classes have
an is-a relationship among each other and objects of one class
acquire properties and features of the other class. The class which
inherits the features is known as the child class, and the class
whose features it inherited is called the parent class. For example,
Class Vehicle is the parent class, and Class Bus, Car, and Bike are
child classes.
INHERITANCE

 Polymorphism- It means many forms. It is the ability to take
more than one form. It is a feature that provides a function or an
operator with more than one definition. It can be implemented
using function overloading, operator overload, function
overriding, virtual function.
POLYMORPHISM

Advantages of OOPs
There are various advantages of object-oriented programming.
 OOPs provide reusability to the code and extend the use of
existing classes.
 In OOPs, it is easy to maintain code as there are classes and
objects, which helps in making it easy to maintain rather than
restructuring.
 It also helps in data hiding, keeping the data and information
safe from leaking or getting exposed.
 Object-oriented programming is easy to implement.
