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
We have provided you the implementation for the `Planet` class. Your task is to ensure abstraction by splitting up the code into **header** and **.cpp** files.

In the code below, `Planet.h` and `Planet.cpp` are empty, whereas `main.cpp` contains the full implementation. The class contains three variables:

1. `radius` - The distance from the center of the planet.

2. `mass` - The mass of the planet.

3. `G` - The gravitational constant.

The `getMass()` function simply returns the mass of the planet and `calculateGravity()` calculates the gravitational strength of the planet.

The end goal is to remove all the implementation of the `Planet` class from `main.cpp`.

Good luck!
