Hello world ! in C++

C++ (pronounced “See plus plus”) is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It 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 C++ in 1983. (read all...)
