Use this tag for questions concerning the use of the C++ programming language and for questions containing code in the C++ language. Avoid using it together with the C tag unless your question is explicitly about code compatibility or differences between C++ and C.
Unless the question explicitly mentions which version of the C++ standard that is uses, the current active version of ISO 14882 is assumed (C++17).
When applicable, always include information about which compiler and target system you are using.
