What is C++? Outstanding Features of C++

In the world of programming languages, few have left as profound a mark as C++. But what is C++? This article by Recruitery delves into the essence of C++, from its definition to its remarkable features. Join us on a journey to uncover the power and versatility that have made C++ a language of choice for developers worldwide.

What Is the Definition of C++?

C++ programming language  

At the beginning of the article, we will find out what C++ is. It is:

  • A general-purpose, object-oriented programming language developed from the C language.
  • Runs on a variety of platforms, from personal computers to embedded devices.
  • Widely used in many different fields, such as software development, game design, database processing, web development, compilers, operating systems, and many other applications.

Outstanding Features of C++

What are the outstanding features that make many users prefer C++?

  • Supports object-oriented programming: Create classes and objects with separate properties and methods; Objects can inherit (inheritance) and use polymorphism (polymorphism) from other classes, creating reusable and maintainable source code.
  • Supports procedural programming: Can be written in a procedural programming style, using functions and variables to perform specific tasks; Compatible with the C language, which means programs written in C can run on C++.
  • Supports low-level programming: Provides access and control over low-level computer resources, such as memory, registers, pointers, etc.; allows writing high-performance programs and optimization for embedded devices.
  • Supports high-level programming: Utilizes high-level programming language features, such as complex data types, standard libraries, templates, exceptions, etc.; Enables writing complex and flexible programs.

Practical Applications of C++

Practical applications of C++ make it stand out among many programming languages. C++ is used in various fields, including:


Used for high graphics, sound, and performance processing (Examples: Counter-Strike, World of Warcraft, FIFA, Call of Duty, etc.).

Database Software

Developed for managing databases due to its ability to process data quickly (Examples: MySQL, MongoDB, Oracle Database, etc.).

Web Development

Used to create web applications that interact with network protocols, web servers, and other web technologies (Examples: Google, Facebook, YouTube, etc.).


Used to develop compilers, parsing, and compiling other programming languages (e.g., GCC, LLVM, Visual Studio, etc.).

Operating Systems

Applied to the development of operating systems due to its ability to control low-level resources of computers and compatibility with the C language (e.g., Windows, Linux, macOS, etc.).


Used to develop applications for computers and mobile devices, allowing for the creation of graphical interfaces and running on multiple platforms (e.g., Adobe Photoshop, Microsoft Office, Skype, etc.).


Used to develop animation software, handling 3D graphics and special effects (Examples: Maya, Blender, Pixar RenderMan, etc.).
