C++ is a powerful general-purpose programming language. It can be used to develop operating systems, browsers, games, and so on. C++ supports different ways of programming like procedural, object-oriented, functional, and so on. This makes C++ powerful as well as flexible.
C++ is a very popular language for performance-critical applications that rely on speed and efficient memory management. It’s used in a wide range of industries including software and game development, VR, robotics, and scientific computing.
C++ Language Features
Some of the interesting features of C++ are:
Object-oriented: C++ is an object-oriented programming language. This means that the focus is on “objects” and manipulations around these objects. Information about how these manipulations work is abstracted out from the consumer of the object.
Rich library support: Through C++ Standard Template Library (STL) many functions are available that help in quickly writing code. For instance, there are standard libraries for various containers like sets, maps, hash tables, etc.
Speed: C++ is the preferred choice when latency is a critical metric. The compilation, as well as the execution time of a C++ program, is much faster than most other general purpose programming languages.
Compiled: A C++ code has to be first compiled into low-level code and then executed, unlike interpreted programming languages where no compilation is needed.
Pointer Support: C++ also supports pointers which are widely used in programming and are often not available in several programming languages.
It is one of the most important programming languages because almost all the programs/systems that you use have some or the other part of the codebase that is written in C/C++. Be it Windows, be it the photo editing software, be it your favorite game, be it your web browser, C++ plays an integral role in almost all applications that we use.
Advantages of C++ Language
C++ has the following 2 features that make it a preferred choice in most of the applications:
Speed: C++ is faster than most other programming languages and it provides excellent concurrency support. This makes it useful in those areas where performance is quite critical and the latency required is very low. Such requirements occur all the time in high-load servers such as web servers, application servers, database servers, etc. C++ plays a key role in such servers.
Closer to hardware: C++ is closer to hardware than most other programming languages like Python, etc. This makes it useful in those areas where the software is closely coupled with hardware and low-level support is required at the software level.
