Learning C++

Learn C++

C++ is a general-purpose programming language that was developed as an extension of the C programming language. It has a rich history dating back to the late 1970s. Here’s a brief overview of the history of C++:

  1. Origins in C:
    • C++ was created by Bjarne Stroustrup, a Danish computer scientist, in the early 1980s. Stroustrup was working at Bell Labs, which was known for the development of the C programming language. He wanted to add features to C that would make it more suitable for systems programming and large-scale software development.
  2. C with Classes (Cfront):
    • In 1983, Stroustrup introduced the first version of C++ called “C with Classes.” It included classes, which are a fundamental feature of C++, along with other object-oriented programming (OOP) features like inheritance and polymorphism. To implement this new language, Stroustrup created a preprocessor called “Cfront” that translated C++ code into standard C code.
  3. Standardization:
    • As C++ gained popularity, a group of developers and organizations recognized the need for a standardized version of the language. The first official C++ standard, known as C++98 or C++03 (after some minor revisions), was published in 1998. This standard defined the core features and syntax of C++.
  4. Evolution and Standardization:
    • C++ continued to evolve with new standards. Notable standards include C++11 (2011), C++14 (2014), C++17 (2017), and C++20 (2020). Each new standard introduced enhancements, additional libraries, and improved language features.
  5. Key Features:
    • C++ is known for its support of both procedural and object-oriented programming paradigms. It provides features like classes, templates, operator overloading, and multiple inheritance. It also introduced the Standard Template Library (STL) for generic programming, which includes data structures and algorithms.
  6. Use Cases:
    • C++ has been widely used in various domains, including systems programming, game development, embedded systems, scientific computing, and high-performance applications. It’s the language behind many popular software and frameworks.
  7. C++ Today:
    • C++ remains a popular and influential language in the software development industry. It has a strong community of developers and continues to receive updates and improvements. C++20 introduced numerous enhancements, and future standards are expected to further refine the language.
  8. Compatibility with C:
    • One of the key design principles of C++ is its compatibility with C. C++ code can include and interact with C code seamlessly, making it easy to incorporate existing C libraries into C++ projects.

Learning C++ for Unreal Engine Game Development: A Comprehensive Guide

If you’re passionate about game development and want to dive into the world of Unreal Engine, learning C++ is essential. Unreal Engine, one of the industry’s leading game development platforms, relies heavily on C++ for creating high-quality, interactive games. Here’s a comprehensive guide tailored to aspiring game developers interested in coding for Unreal Engine:

1. Establish a Strong C++ Foundation

Before you jump into Unreal Engine-specific development, it’s crucial to grasp the fundamentals of C++. Start with these building blocks:

Variables and Data Types

Learn how to declare, initialize, and manipulate variables, including integers, floats, and characters.

Control Structures

Master control flow mechanisms like `if`, `for`, and `while`. These are vital for implementing game logic and interactions.


Understand how to define and call functions in C++, as they are essential for organizing and reusing code.

2. Embrace Object-Oriented Programming (OOP)

Unreal Engine heavily utilizes object-oriented programming principles. Get comfortable with these core OOP concepts:

Classes and Objects

Comprehend the role of classes and objects in C++. In Unreal Engine, game entities are often represented as objects with associated behaviors.


Learn how to create new classes based on existing ones. This feature promotes code reuse and hierarchy in game development.


Explore polymorphism, which allows you to treat objects of different classes as instances of a common base class. This enhances flexibility when managing various game elements.

3. Leverage Unreal Engine’s API

Unreal Engine provides a rich application programming interface (API) that simplifies many game development tasks. Familiarize yourself with Unreal’s API to access features like rendering, physics, and input.

 4. Dive into Unreal’s Gameplay Framework

Unreal Engine has a well-defined gameplay framework, including classes like Actors, Controllers, and Pawns. Understand how these components work together to create dynamic gameplay experiences.

5. Blueprint vs. C++

Unreal Engine offers a visual scripting system called Blueprints, which is excellent for rapid prototyping and certain game logic tasks. Learn when to use Blueprints and when to implement functionality in C++ for optimal performance and control.

6. C++ Memory Management

Efficient memory management is critical in game development. Learn how to allocate and deallocate memory, manage resources, and prevent memory leaks. Unreal Engine’s smart pointers (`TSharedPtr` and `TWeakPtr`) can simplify memory management.

 7. Unreal Engine-Specific Features

Explore Unreal’s unique features, such as Blueprint-Native Communication, Unreal’s Garbage Collection system, and the Unreal Build System (UBT), which compiles your C++ code into the engine.

8. Projects and Practice

Hands-on experience is invaluable. Start with small game projects and gradually work your way up to more complex ones. Unreal Engine provides starter templates and sample projects to help you get started.

9. Online Resources and Communities

Unreal Engine has a vibrant online community. Utilize resources like the official Unreal Engine documentation, forums, and video tutorials. Engage with fellow developers on platforms like Unreal Engine AnswerHub and GitHub.

10. Unreal Engine Courses and Books

Consider enrolling in Unreal Engine courses or reading books dedicated to Unreal Engine development. These resources can provide structured learning and in-depth insights into the engine’s capabilities.
