Object Oriented Programming

Video Summary

Object-oriented programming (OOP) is a programming paradigm that organizes software around objects. In OOP, objects are defined as data structures that contain both data and procedures (known as methods). OOP allows programmers to create reusable code and to think about problems in a more natural way. Here are some of the benefits of OOP: * **Reusability:** OOP allows programmers to create reusable code by defining objects that can be used in multiple programs. * **Natural problem-solving:** OOP allows programmers to think about problems in a more natural way by representing them as objects. * **Abstraction:** OOP allows programmers to hide the details of how an object works, making it easier to use. * **Encapsulation:** OOP allows programmers to protect data from being accessed by unauthorized code. OOP is a powerful programming paradigm that can be used to create complex and efficient software.
