What is C++ used for? Useful real-life applications of C++


Every single person who has programming knowledge, should have thought once in his or her life what is C++ used for. A strong general-purpose programming language is C++. Operating systems, browsers, games, and other applications can all be created with it. Different programming paradigms, including procedural, object-oriented, functional, and others, are supported by C++. Because of this, C++ is both strong and adaptable.

You will find some FAQs about What is C++ used for at the end of the post.

What is C++


The best object-oriented programming language for developing complex applications is thought to be C++. Since C is derived from C++, the programming language C++ is referred to as the superset of C. C++ is the foundation for Java, another computer language.

C++ is used by large companies, including Facebook, LinkedIn, Microsoft, Opera, Evernote, and NASA. Evernote switches from.NET to C++ for faster speed and better graphics.

Some features of C++

C++ has a very complex syntax, and it is not that easy to write code in C++. 

The C++ programming language is a compiled language. C++ compilers take C++ source code and turn it into object code, which they then execute to produce output.

In C++, the declaration and data type of variables are verified at the time of compilation because it is a statically typed language. This process can make the code error-free at the time of run.

The syntax in C++ is well structured because code is separated by blocks and semicolons are used to denote the end of a statement.

Reasons for what is C++ used for are listed below.


In a wide range of industries, C++ is used. See the list below for some of the most prominent, fascinating, and even unexpected real-world C++ applications, for what is C++ used for.

Operating systems

From MacOS and Windows to mobile operating systems like iOS, C++ is a crucial component of well-known operating systems. Operating systems must, in general, manage system resources quickly and effectively. Developers can organize their code to make even the tiniest components of an operating system quick and energy-efficient thanks to C++’s low-level (almost machine code) capabilities.

Game development


One of the most popular programming languages for creating video games is C++. Games like World of Warcraft, Counter-Strike, and StarCraft, as well as game engines like Unreal Engine and gaming platforms like the Xbox, PlayStation, and Nintendo Switch, have all been produced using it.

Resource-intensive tasks are frequently used in gaming, such as creating visuals or supporting multiplayer matches. By enabling programmers to precisely control how data structures and memory allocation are handled, C++ aids in resource optimization.

GUI-Based Programs

The creation of desktop and GUI-based apps uses C++ as well. The majority of Adobe’s software, including Photoshop, Illustrator, and other programmes, are created using C++

Web Browsers

People do not like to wait for their online sites to load, thus web browsers need to be quick. Because of this, the majority of browsers are created in C++. Mozilla Firefox was entirely created in C++. C++ is used in part in Google programmes like Chrome and Google File System.

Access to databases

Additionally, database software or open-source database software is created using this language. One of the most well-liked and commonly used database management programmes is MySQL, which serves as an illustration for this. Time, money, business processes, and bundled software are all saved as a result. Wikipedia, Yahoo, YouTube, and other programmes that access databases also use C++. Another illustration is Bloomberg RDBMS, which assists in giving investors access to real-time financial information. It is mostly written in C++, which facilitates fast, precise database access to give corporate and financial information as well as global news.

Media Access

The creation of a media player and the administration of audio and video files are likewise done with C++. One example is the C++-written Winamp Media Player, which enables us to access and share music and video files as well as enjoy music. Additional features include art support and audio and video streaming. Access to online radio stations is also provided.

Other Uses

Computer-aided design systems and medical and technical applications use it. These programmes are comparable to MRI scanners and CAM systems, which are mostly employed by hospitals, municipal, state, and federal governments, as well as other departments involved in mining and construction, among other things. When performance is taken into account for any developing application, C++ is thought of as the first preferable language to utilize by developers.


In this post, we have discussed What is C++ used for? We have discussed some real-life application examples of what is C++ used for. You can find C++ being used in some capacity almost everywhere! As this is the most popular and one of the most used programming languages.

FAQS about What is C++ used for.

Question: What is C++ used for mainly?

Answer: C++, sometimes known as “C-plus-plus,” is a general-purpose coding language that has been used for more than 40 years to create browsers, operating systems, programmes, software engineering, data structures, and other things.

Question: Where is C++ now used?

Answer: It is utilized when a low-level programming language is required, much like C. While C++ is frequently used for graphically intensive software like games, programmes for editing photos and videos, and browsers, C is more frequently employed for embedded systems and OS kernels.
