Study Notes
History of Object Oriented Programming
- The term "Object-Oriented Programming" (OOP) was coined by Alan Kay around 1966.
- The language Simula, developed in 1967, was the first to feature OOP.
- OOP grew in popularity in the 1990s due to C++.
What Is Object-Oriented Programming?
- OOP is about creating "objects", which are groups of interrelated variables and functions.
- OOP is based on the concept of objects and classes, making it close to real-world scenarios.
Key Concepts of OOP
- Classes and objects
- Methods (functions of an object)
- Properties (variables of an object)
- Encapsulation (data hiding)
- Inheritance (hierarchical relationships between classes)
Advantages of OOP
- Provides a clear program structure
- Easy maintenance and modification of existing code
- Enhances program modularity
- Presents a good framework for code libraries
- Imparts code reusability
Four Pillars of Object-Oriented Programming
Encapsulation
- Hides unnecessary details and makes it easier to manage the program structure
- Each object's implementation and state are hidden behind well-defined boundaries
Inheritance
- Allows for code reuse
- Captures a hierarchical relationship between classes and objects
Abstraction
- Hides details and exposes only essential features of a concept or object

Description
Explore the differences between Object-Oriented Programming (OOP) and Procedure-Oriented Programming (POP) in this quiz. Learn how OOP provides a clearer and less complex structure compared to POP, allowing for code reusability through features like inheritance.
