Understanding Inheritance in OOP

In object-oriented programming, Inheritance is a mechanism where a new class (derived class) acquires the properties and behaviors (data members and member functions) of an existing class.

Types of Inheritance

• Single Inheritance: In single inheritance, a single derived class is inherited from only one base class. It is the simplest form of inheritance.
• Multiple Inheritance: Multiple inheritance occurs when a single derived class is inherited from more than one base class.
• Hierarchical Inheritance: In this type, multiple derived classes are inherited from a single base class.
• Multilevel Inheritance: In multilevel inheritance, a derived class is inherited from another derived class, creating a chain of inheritance.
• Hybrid
