What is CPP?

Cpp programming  (pronounced see plus plus) is general-purpose programming language. Cpp programming is regarded as a "middle-level" language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell Labs as an enhancement to the C programming language and originally named C with Classes. It was renamed Cpp programming in 1983.
As one of the most popular programming languages ever created, C++  programming is widely used in the software industry. Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games.
