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++

In the last lesson, we have seen that `Vehicle` class attributes are shared by the other two classes(`Car` and `Ship`). 

## Vehicle as a Base Class

We can consider the `Vehicle` class as a `base` class as it has common attributes.

## Derived Classes

*Cars* and *Ships* are considered as `derived` classes as they're inheriting properties from `vehicle` class.

## Modes of Inheritance

There are three modes of class inheritance: `public`, `private` and `protected`. The basic syntax for inheritance is given below:

```C++
class derivedClassName : modeOfInheritance baseClassName
```

We use the keyword **public** to implement **public** inheritance.

# Vehicle as a Base Class

We can consider the `Vehicle` class as a `base` class as it has common attributes.

# Derived Classes

*Cars* and *Ships* are considered as `derived` classes as they're inheriting properties from `vehicle` class.

# Modes of Inheritance

There are three modes of class inheritance: `public`, `private` and `protected`. The basic syntax for inheritance is given below:

```C++
class derivedClassName : modeOfInheritance baseClassName
```

We use the keyword **public** to implement **public** inheritance.

In this lesson, we'll be learning about how a base class attributes are available to the derived classes and how to define base and a derived class.
