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.

C++ is profiled on the APIs.io network. Tagged areas include C++, Compiled Languages, Generic Programming, ISO Standard, and Object-Oriented.

C++’s developer surface includes getting-started guide, FAQ, GitHub presence, Stack Overflow tag, engineering blog, and 12 more developer resources.
