OOP stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.
OOP focuses on creating objects that contain both data and methods to manipulate that data.

Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Inheritance allows a class to reuse code from another class.
Types of inheritance include single inheritance, where a class inherits from only one parent class, and multiple inheritance, where a class inherits from multiple parent classes.
Example: Class B inherits from Class A, so Class B can access
