Inheritance in Object-Oriented Programming (OOP) is a mechanism that allows classes to derive properties and methods from other classes, promoting code reusability and hierarchical class structures. It enables developers to create software that is more maintainable and scalable, with the ability to extend existing functionalities. The concept supports various inheritance patterns, such as single, multiple, and multilevel inheritance, each serving different programming needs and scenarios.

Inheritance allows subclasses to inherit properties and methods from a superclass, promoting code reusability and establishing hierarchical relationships between classes
Superclass and Subclass
The superclass provides foundational attributes and behaviors that subclasses can inherit and potentially override or extend
Single Inheritance
In single inheritance, a subclass inherits from only one superclass, while some languages support multiple inheritance
Polymorphism and Access Modifiers
Polymorphism, facilitated by inheritance, allows objects of different classes to be treated as objects of a common superclass, while access modifiers determine the accessibility of class members
Inheritance promotes code reusability, aids in maintenance and evolution of software, enhances modularity, and allows for systematic organization within applications
In single inheritance, a subclass inherits from one superclass, making it the simplest form of inheritance
Multiple inheritance allows a subclass to inherit from several superclasses, while multilevel inheritance involves a linear inheritance path through several classes
Hierarchical Inheritance
Hierarchical inheritance features several subclasses deriving from a single superclass
Hybrid Inheritance
Hybrid inheritance is a combination of two or more types of inheritance
Inheritance is used in various sectors, such as single inheritance in GUI frameworks, multilevel inheritance in game development, and hierarchical inheritance in content management systems
Java
Java uses the 'extends' keyword to establish inheritance relationships
C++
C++ uses the colon symbol and access specifiers to denote inheritance
Python
Python indicates inheritance through the use of parentheses
Different programming languages utilize inheritance to facilitate code reuse and extend system capabilities in various applications

______ allows for the extension of existing code by ______, enhancing consistency and speeding up ______.
Inheritance
subclasses
development
01
Define single inheritance.
Single inheritance is when a subclass inherits from only one superclass.
02
Explain multiple inheritance.
Multiple inheritance allows a subclass to inherit from more than one superclass.
