Parent and Child Classes in OOP

1. Parent and Child Classes in OOP Understanding Inheritance in Object-Oriented Programming

2. Introduction to OOP Object-Oriented Programming (OOP) is a paradigm based on the concept of "objects.“ It helps in organizing code in reusable and modular components. Key concepts: Encapsulation, Abstraction, Inheritance, and Polymorphism.

3. What are Parent and Child Classes? Parent Class (Base/Superclass): A general class that contains common attributes and methods. Child Class (Derived/Subclass): A class that inherits the properties and methods of the parent class and can have additional specific attributes or methods.

4. Inheritance in OOP Inheritance allows a child class to reuse the methods and properties of a parent class. Promotes code reuse and reduces redundancy. Child classes can extend or modify the behavior of the parent class.

5. Syntax of Inheritance (Example in Python) NOTE: Child inherits from Parent and can use both parent and child methods.

6. Example of Parent Class (Animal) Parent class Animal with common properties like name and age.

7. Example of Child Class (Dog) Dog class inherits from Animal and adds a specific method bark.

8. Key Features of Parent and Child Classes Method Overriding: Child class can override methods from the parent class. Multiple Inheritance: A child class can inherit from multiple parents in some languages (e.g., Python). Extensibility: Child classes can extend the functionality of the parent class.

9. Advantages of Using Parent-Child Classes Code Reusability: Common functionality is written once in the parent class. Maintainability: Centralized updates in the parent class reflect in all child classes. Flexibility: Child classes can extend or specialize the behavior of the parent class.

10. Conclusion Parent-child classes (inheritance) are fundamental to OOP. Inheritance allows for creating hierarchical relationships between classes. Promotes cleaner, more organized, and maintainable code.
