Explore OOP in C++ to write cleaner, modular, and scalable code. Learn classes in C++, data hiding, encapsulation, abstraction, inheritance, and polymorphism in C++.

Become  a C++ Programmer

This module aims to teach us how to write cleaner, more modular, and scalable code in C++ by providing an understanding of OOP in C++. We'll start with the basics of object-oriented programming and build up to advanced concepts such as inheritance, data hiding, and polymorphism. Along the way, we'll explore how each concept applies to C++ and how various C++ features facilitate OOP.

Object-Oriented Programming in C++

## Problem Statement

Write a `Rectangle` *class* having **two** `float` type variables for `length` and `height`, a **parametrized** *constructor* and **two** *member* functions called `perimeter` and `area` which *return* **perimeter** and **area** of the **rectangle** respectively.
### Input
Length and width of the rectangle
### Output
Perimeter of rectangle and Area of rectangle

### Sample Input
```C++
length = 2, height = 10

```

### Sample Output
```C++
Perimeter = 24
Area = 20
```
