C++ is a high-level, general-purpose programming language designed for system and application programming. It is an extension of the C programming language. C++ is an object-oriented, multi-paradigm language that supports procedural, functional, and generic programming styles. One of the key features of C++ is its ability to support low-level, system-level programming, making it suitable for developing operating systems, device drivers, and other system software. At the same time, C++ also provides a rich set of libraries and features for high-level application programming, making it a popular choice for developing desktop applications, video games, and other complex applications.

C++ is a one of the foundation languages of modern programming. It has evolved out of the basic C into a very powerful tool in modern programming. The versions of C++ started with C++ 98, and are now upto C++ 20. After the update of C++ 11, all modern updates are known collectively as modern C++. These new models have vast and new features, making the language more user- friendly and better feature-equipped. Some of these new concepts were already part of other new languages like Ethereum, Ruby, Python, and Javascript, and with the introduction of these concepts in C++, programming has become more efficient today.
