C++

What is C++?

C++ is an object-oriented language derived from C, and invented by Bjarne Stroustrup, while working at AT&T's Bell Labs. It is widely used for systems-level programming, and building applications on Windows and various Unix operating systems (Linux, *BSD, etc). It supports many interesting features, such as multiple inheritance (although usage of this is widely discouraged), generics, and sophisticated information-hiding constructs such as "friend classes". Notably, the generics features are Turing-complete, and can be used for a form of metaprogramming in which complex calculations are performed at compile-time instead of runtime. It is a common practice for organizations to define a coding standard in which many of the features of C++ are strictly forbidden in an attempt to ensure that code produced is comprehensible and predictable. Prominent implementations of C++ include Microsoft's Visual C++, the GNU Compiler Suite (GCC), and LLVM's Clang compiler.
