Study Notes

Object-Oriented Programming (OOP)

OOP is a computer programming model or paradigm that combines data and functions into a single unit.
It's a methodology that teaches developers to create secure and realistic software.

Key Concepts

Object: Any entity that has state (data) and behavior (functionality) is called an object, also known as a run-time entity.
Class: A class is a user-defined data type that contains information about member variables, member methods, constructors, and destructors.
Attributes: An attribute is a changeable component of a program that can be set to different values.

Pillars of OOP

Encapsulation

Encapsulation is the wrapping or bundling of data and functions into a single unit.
It provides data security.

Remaining Pillars of OOP

Inheritance
Polymorphism
Abstraction

Miscellaneous

The world's first OOP language was SIMULA 67.
