What is C++ used for?

C++ is one of the most popular programming languages used for building

  • Operating Systems
  • Games
  • Web Server
  • Embedded Systems
  • Compilers
  • Game Engines
  • Telecommunication Systems
  • Machine Learning Models
  • Artificial Intelligence
  • Desktop Applications
  • Augmented Reality Applications
  • Virtual Reality Applications
  • Mobile Applications
  • Database Management Systems
  • Robotics
  • Predictive Maintenance

and more.

C++ was designed with an orientation toward systems programming and embedded resource-constrained software. C++ is used to code very close to the hardware, one of the guiding principles of C++ is that there should be no language beneath C++ (except Assembly Language).

C++ is among some of the fastest and high performant programming languages, it is one of the few high-level programming languages in which petaFLOPS computations have been achieved, others being C, Julia, and Fortran.

Here is what C++ is used for.


C++ is one of the preferred languages to develop Operating systems. Some of the Operating Systems developed with C/C++ include Blackberry OS, Mac OS (some parts), Windows OS (some parts), and Linux (some parts).

If you are interested in developing operating systems of your own, C++ is one of the best programming languages to pick up.


C++ is the most popular programming language for developing games and game engines. There are many game engines that were developed using C++, some of the popular ones include Unreal Engine, Unity 3D, 4A Engine, CryEngine, Godot, Lumberyard, and many others.

C++ is also popular for game scripting, it is used in Unreal Engine, CryEngine, and many others. Having a good understanding of C++ can help you to develop powerful AAA games.

Unreal Engine is one of the most advanced, powerful, and popular platforms for making 2D and 3D games, it uses the C++ programming language for programming the game logic.

Unreal Engine has also a marketplace that has a lot of resources ranging from art assets to models, sounds, environments, code snippets, and more. Some of them are free while others can be paid for.

Some of the popular games made with Unreal Engine include Fortnite, Brothers in Arms, Golden Eye: Rogue Agent, Medal of Honor, Shadow Ops, Shrek 2, Star Wars, Spider-man 2, Batman Arkham City, DC Universe Online, Mortal Kombat, Transformers, Crash Bandicoot, and many others.

Unreal supports many platforms, once you are done developing your games, you can deploy to different platforms such as Android, iOS, tvOS, macOS, Windows, Linux, Playstations, Xbox, Nintendo, Stadia, WebGL, Oculus VR, PSVR, ARCore, etc.


An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system.

Embedded systems are commonly found in consumer, industrial, automotive, home appliances, medical, telecommunication, commercial, and military applications.

You use platforms like Qt and many others to make embedded systems.


A compiler is a program that converts instructions into machine code or lower-level form so that they can be read and executed by a computer. C++ is one of the best languages to develop compilers because of its close communications with the hardware.


C++ machine learning and artificial intelligence libraries can be used for linear and nonlinear optimization, developing and training models, kernel-based learning algorithms, neural networks, classification, regression, forecasting, etc. They can also be used in deep learning for Data preparation, design, and simulation.

C++ has many popular machine learning libraries that help a lot of developers and engineers to work on machine learning projects. Some of the popular C++ machine learning libraries include

  • MLPack,
  • TensorFlow C++ API,
  • Shark ML,
  • OpenNN,
  • DyNet,
  • Shogun,
  • Armadillo, and many others.


C++ is a popular language for developing desktop applications. You can use Windows Visual studio to make desktop apps for windows.

Some of the popular apps made with C++ include Adobe graphics applications (Photoshop, Dreamweaver, Illustrator, Fireworks, Premiere Pro, AfterEffects, etc.) OBS, MTorrent, Internet Download Manager, Unity build, Adobe Flash, Google Chrome, Shazam, Sublime Text, Earth3D, etc


One of the philosophies of C++ is that there should be no language beneath C++ (except Assembly Language). This ability to program very close to the hardware makes C++ a wonderful choice for Robotics projects.

Another implementation is the use on Arduino boards (an Open-source electronic prototyping platform enabling users to create interactive electronic objects). Arduino boards enable users to create electronic objects (Robots, small computing devices, etc.) using C/C++.


A Browser is a computer program with a graphical user interface for displaying and navigating between web pages. You are using one right now to read this article and browse through the internet.

Most of these powerful pieces of Software have been written in C++. Examples include Chromium, Opera, Firefox, Yendex, etc.


You can also get a job as a native mobile app developer. C++ can also be used to develop Mobile applications. You can use a platform like Qt to develop C++powered applications.

There are also cross-platform tools available in Visual Studio that can be used to make C++ powered mobile applications for Android and iOS.

It can be seen that there are a lot of opportunities for C++ programmers to work on a wide scale and range of projects in different fields.


It can be seen that C++ is very popular and is used for a variety of projects in different industries. If you desire to do systems programming, C++ is the best programming language to pick up.
