Data structures play a pivotal role in OOP by providing structure to store data, with methods (functions) that define the way data is manipulated within those structures.

Object Oriented Programming

object-oriented programming software engineering data structures programming paradigms
Object-Oriented Programming (OOP) is a programming paradigm that uses 'objects' to design software. It allows for structuring programs so that properties and behaviors are bundled into individual objects.

Introduction to Object-Oriented Programming

Object-Oriented Programming, often abbreviated as OOP, is a programming paradigm centered around the concept of objects. These objects are instances of classes, which can be thought of as blueprints for creating individual objects. OOP is designed to allow programmers to create more flexible, modular, and reusable code.

Core Concepts of OOP

  • Classes and Objects: A class is a blueprint for creating objects. An object is an instance of a class.
  • Encapsulation: Encapsulation refers to the bundling of data with the methods that operate on that data.
  • Inheritance: Inheritance is a mechanism where a new class inherits properties and behaviors from an existing class.
  • Polymorphism: Polymorphism allows for methods to do different things based on the object it is acting upon.
  • Abstraction: Abstraction is the concept of hiding the complex reality while exposing only the necessary parts.

Benefits of OOP

OOP helps in making the code manageable and organized. It helps in the reusability of code through inheritance, provides a clear modular structure for programs, and aids in the abstraction and encapsulation of complex processes.
