Lecture 25: Inheritance in Object-Oriented Programming (OOP) | Tutorial with Real-World examples

Inheritance is one of the core pillars of Object-Oriented Programming (OOP) and plays a vital role in building reusable, scalable, and maintainable software systems.
In this lecture, we provide a complete and easy-to-understand explanation of Inheritance, designed especially for computer science students, software engineering learners, and beginner to intermediate programmers.

This video explains how inheritance allows one class to acquire the properties and behaviors of another class, promoting code reusability, reduced redundancy, and better program structure. The lecture gradually moves from basic concepts to advanced understanding, ensuring clarity at every stage.

🔹 What You Will Learn in This Lecture:

What is Inheritance in Object-Oriented Programming

Why inheritance is important in software development

Relationship between Parent Class (Superclass) and Child Class (Subclass)

Types of inheritance:

Single Inheritance

Multilevel Inheritance

Hierarchical Inheritance

Multiple Inheritance (conceptual understanding)

How inheritance improves:

Code reusability

Maintainability

Extensibility

Real-world examples of inheritance (e.g., Vehicle, Animal, Employee systems)

Common advantages and limitations of inheritance

Best practices for using inheritance effectively

This lecture is especially useful for:

OOP concepts for exams and interviews

University-level programming courses

Software architecture and design fundamentals

Learning inheritance in languages like Java, C++, Python, and C#

By the end of this video, you will have a strong conceptual foundation of inheritance, enabling you to apply it confidently in real programming projects and advanced OOP topics like polymorphism, abstraction, and design patterns.
