C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. This tag should be used for any question which requires knowledge or expertise with the C++ programming language. This is a general tag which is used for any of the C++ language standards (C++98, C++11, C++17, etc.). The question should identify the compiler being used, the operating system, and which of the C++ standards is being targeted.
