C++ is a high-level, general-purpose programming language created by Danish computer scientist Bjarne Stroustrup. It was first released in 1985 as an extension of the C programming language, and has since expanded significantly over time. C++ is an object-oriented programming language that gives a clear structure to programs and allows code to be reused, lowering development costs. It is a superset of the C language, and allows software developers to define their own data types and manipulate them using functions and methods. C++ also allows low-level programming and provides access to memory, enabling fast and efficient execution of code. It also supports generic programming using templates, which let code be written in a generic form and reused for different data types.
C++ was designed with systems programming and embedded, resource-constrained software and large systems in mind, with performance, efficiency, and flexibility of use as its design highlights. It is used in fields such as system software, game development, embedded systems, scientific computing, and high-performance applications. C++ is portable and can be used to develop applications that can be adapted to multiple platforms. The language was updated 4 major times in 2011, 2014, 2017, and 2020 to C++11, C++14, C++17, C++20.
