C++
C++ is a general-purpose, statically typed, compiled programming language created by Bjarne Stroustrup as an extension of C. C++ supports object- oriented, generic, and functional programming and is widely used in systems programming, game engines, embedded systems, scientific computing, finance, and high-performance services. The language is standardized by ISO/IEC JTC1/SC22/WG21 with current revisions including C++20 and C++23. C++ does not expose a network/HTTP API; this index captures the language home, standards process, reference documentation, and ecosystem resources.
