According to comments on How to make a variadic macro (variable number of arguments) C99 has variadic macros, but the then-current C++ does not.

However, that was over a decade ago, and I'm interested in the new versions of C++.

Does C++ 20 or 23 have variadic macros? If not, are any stakeholders trying to get them on the agenda for future versions?

C++ has had variadic macros like C since day one. They all come from the C preprocessor that both C and C++ use – NathanOliver Jun 27 '23 at 12:24

That said, C++11 introduced [variadic templates](https://en.cppreference.com/w/cpp/language/parameter_pack) which should be preferred. – NathanOliver Jun 27 '23 at 12:26

Not since day one, but since C++11. https://en.cppreference.com/w/cpp/preprocessor/replace – maxplus Jun 27 '23 at 12:26

@NathanOliver-IsonStrike - Officially? No. C++ defines preprocessing on its own, not by simple defferal. Only C++11 offically added variadic macros. – StoryTeller - Unslander Monica Jun 27 '23 at 12:26

*Does C++ 23 have variadic macros?* Yes. C++ has had variadic macros since C++11. – Eljay Jun 27 '23 at 12:31

If possible try to avoid macros, C++ has (variadic) templates. So what are you trying to solve with variadic macros? – Pepijn Kramer Jun 27 '23 at 12:59
