+# Object Oriented Programming
+
+<img src="https://i.imgur.com/qPsUYyd.jpg" alt="meme" style="zoom:50%;" />
+
+## Introduction
+
+- A programming paradigm
+- Allows:
+  - Model objects
+  - Make objects interact with each other
+- Objcts refer to complex variables
+
+## Benefits and motivation
+
+- Modularity
+- Abstraction
+- Productivity and reusability
+- Security and encapsulation
+
+## Concrete example
+
+- When we develop a game with cars inside
+- We develop the car one time and all other games can re-use the base of the car that we created
+- We have access to characteristics
+  - Model
+  - Color
+  - Fuel type
+  - ...
+- We also have the behavior of the car
+  - Start
+  - Accelerate
+  - Stop
+
+## Object
+
+- Data part: object characteristcs
+  - Attributes
+  - Properties
+  - Fields
+  - ...
+- Code part = oject behavior
+  - Methods
+  - Procedure
+
+## Class
+
+- Object = classs instance
+- Class
+  - New data type
+  - Collection of objects
+- Figuratively
+  - Class = mold
+  - Object = cake
+- Class at compilation VS object at runtime
+
+```csharp
+public class MyFirstClass {
+  public MyFirstClass() {} //constructor
+}
+MyFirstClass c = new MyFirstClass(); //new object
+```
+
+## Modelization
+
+- First mandatory step
+-
