- Data abstraction The ability to hide complex implementation details of a class and present only necessary information to the outside world, making it easier to use.
- Data Encapsulation The ability to keep data and methods that operate on that data into a single unit, known as a class, to prevent unauthorized access & manipulation.
- Classes and Objects OOP is based on the concept of classes and objects, with classes serving as blueprints for creating objects that have their own data and behavior.
- Inheritance It allows classes to inherit properties & methods from other classes, enabling developers to create a hierarchy of classes with shared attributes & behaviors.

ObjectOrientedProgramming(also known as OOPs) is a programming paradigm where the complete software operates as a bunch of objects talking to each other. An object is a collection of data and the methods which operate on that data.
The main advantage of OOP is better manageable code that covers the following: 1. The overall understanding of the software is increased as the distance between the language spoken by developers and that spoken by users. 2. Object orientation eases maintenance by the use of encapsulation. One can easily change the underlying representation by keepi...
A classis a building block of Object Oriented Programs. It is a user-defined data type that contains the data members and member functions that operate on the data members. It is like a blueprint or template of objects having common properties and methods.
An objectis an instance of a class. Data members and methods of a class cannot be used directly. We need to create an object (or instance) of the class to use them. In simple terms, they are the actual world entities that have a state and behavior.
The main feature of the OOPs, also known as 4 pillars or basic principles of OOPs are as follows: 1. Encapsulation 2. Data Abstraction 3. Polymorphism 4. Inheritance
Encapsulation is the binding of data and methods that manipulate them into a single unit such that the sensitive data is hidden from the users It is implemented as the processes mentioned below: 1. Data hiding:A language feature to restrict access to members of an object. For example, private and protected members in C++. 2. Bundling of data and me...
Abstraction is similar to data encapsulation and is very important in OOP. It means showing only the necessary information and hiding the other irrelevant information from the user. Abstraction is implemented using classes and interfaces.
The word “Polymorphism” means having many forms. It is the property of some code to behave differently for different contexts. For example, in C++ language, we can define multiple functions having the same name but different working depending on the context. Polymorphism can be classified into two types based on the time when the call to the object...
The idea of inheritance is simple, a class is derived from another class and uses data and implementation of that other class. The class which is derived is called child or derived or subclass and the class from which the child class is derived is called parent or base or superclass. The main purpose of Inheritance is to increase code reusability. ...
Access specifiers are special types of keywords that are used to specify or control the accessibility of entities like classes, methods, and so on. Private, Public, and Protectedare examples of access specifiers or access modifiers. The key components of OOPs, encapsulation and data hiding, are largely achieved because of these access specifiers.
