What does the C++ Course include?

Welcome to the world of C Plus Plus! This course will teach you all about this powerful programming language. Here’s a quick overview of what you’ll learn:

Introduction to C++: In this section, you’ll gain a detailed understanding of C Plus Plus. This includes its origins and its relationship with the C language. You’ll learn why C++ is popular for programmers and how it differs from other languages. You’ll lay a strong foundation for further exploration by grasping the basics of procedural programming.
Control Structures, Expressions, and Tokens: This part enables you to understand the core elements of C++ programming. It includes loops, conditionals, and the building blocks of code. You’ll discover how to use control structures to make decisions and iterate through data efficiently. Understanding expressions and tokens will enable you to construct meaningful program instructions and commands.
C++ Functions: Functions are crucial for organizing and reusing code in C++. You’ll explore different types of functions, including how to define, call, and pass arguments to them. By mastering functions, you’ll enhance the modularity and readability of your code. This will make it easier to maintain and debug.
Objects and Classes: Object-oriented programming (OOP) is a paradigm revolutionising how we design and structure software. In this section, you’ll learn about classes, objects, and the building blocks of OOP in C++. You’ll understand how to encapsulate data and behaviour within objects, fostering code reusability and abstraction.
Pointers and Memory Management: Pointers are powerful tools for managing memory and accessing data directly in C++. This section introduces you to pointers and how they work under the hood. You’ll learn to allocate and deallocate memory dynamically, avoiding memory leaks and optimizing resource usage in your programs.
Constructor and Destructor: Constructors and destructors are special member functions that are crucial in managing objects in C++. You’ll discover how constructors initialize objects when they’re created and how destructors clean up resources when objects are destroyed. Understanding these concepts is essential for effective resource management and preventing memory-related issues in your programs.
Operator Overloading and Conversion Types:C++ allows you to redefine the behaviour of operators and perform customs operations on user-defined types through operator overloading. You’ll explore how to overload operators to work with your own classes and data types, enhancing the expressiveness of your code. Additionally, you’ll learn about type conversions, which enable seamless transitions between different data types, improving code flexibility and readability.

What is Class in C Plus Plus?

Think of a class as a blueprint for creating something. Just like how a blueprint for a house tells you what rooms it has and how they’re laid out, a class in C Plus Plus tells your program what data and actions an object based on that class will have.

How Does it Work?

Say we have a class called “Car”. This class would contain all the information and actions that any car in our program would need, like its speed, color, and the ability to accelerate.

Creating Objects

Once we have our blueprint (the class), we can create actual objects based on it. Each object is like an instance of the class, just like how each house built from a blueprint is an instance of that design. So, if we have a class called Car, we can make objects like “myCar” or “yourCar”.

Accessing Data and Actions

With our objects, we can access the data (like the car’s color) and actions (like accelerating) defined in the class. We do this using a dot (.) followed by the name of the data or action we want to access, and the object it belongs to. For example, to find out the color of myCar, we might say myCar.color.

Public, Private, and Protected

In C Plus Plus, we can control who can see and use the data and actions inside a class. We can mark them as “public”, “private”, or “protected”. If something is public, it means anyone can access it. If it’s private, only the class itself can use it. Protected is kind of in between.

Mastering Object-Oriented Programming in C Plus Plus

In C Plus Plus, object-oriented programming (OOP) can become easy, thanks to its support for the four pillars:

Encapsulation: This is more like a protective shield around your data. It bundles data and methods into a single unit, hiding the internal workings and preventing outside interference. This helps keep your code organized, secure, and easier to manage.
Data Hiding: Look for the right ways to control access to your data; if yes, then learn to do it efficiently with C++. It allows only authorized parts of your program to interact with it. This enhances security and prevents unintended modifications, ensuring the integrity of your code and promoting modular design.
Inheritance: this allows you to create new classes based on existing ones, inheriting their attributes and behaviours. This promotes code reuse and facilitates the creation of hierarchies, where classes share common characteristics while adding their unique features. It’s like building blocks for your code and adding to its efficiency and scalability.
Polymorphism: This pillar lets you treat objects of different classes in a unified manner. This means you can curate code that works interchangeably with objects of a base class and its derived classes. It enhances flexibility, allowing you to write more adaptable and reusable code while simplifying complex systems and promoting code clarity.

With a solid understanding of these four pillars, you’ll unlock the full potential of object-oriented programming in C++, empowering you to create robust, modular, and flexible software solutions.
