2 years ago this was asked: When did the "c++" tag start to imply C++11 by default?

1 year ago this was asked: When submitting an answer, when is it ok to use C++11?

Many questions are tagged just C++ and not C++11, but the accepted answer uses C++11 features.

Now that C++14 is around the corner, and C++11 is the defacto standard version:

Is it finally time to stop expecting the C++11 tag if acceptable answers can use C++11 features? Or even if the question includes C++11 features?

Should the C++11 tag be depricated (until C++14 becomes generally adopted) and not request: "Please tag questions about C++11 with the C++ tag, along with the C++11 tag."

Should the C++03 tag be expected to be used to denote questions where C++11 features should not be used in an answer? And state something like, "Please use this tag if the current standard C++11 features cannot be used"

Unlike some other programming languages it is not clear from the question if C++11 features can be used in the answer and in fact some answers may include them and others may not

  • Having said that, I think Jeff's attitude there was pretty severe. We routinely tag async C# questions with the C# tag (because, y'know, C#), and with the C#-5.0 tag because C# 5.0 is required to use async. We also tag questions with, say, .NET-3.5, if the question asker is confined to using a version of the .NET Framework no higher than that (it happens).

  • @RobertHarvey - this is not asking which tag to use, but rather, asking if a tag change is warrented at this time

    I didn't provide some relevant guidance? OK, then let me spell it out: no, a change is not required. In the same manner that C# is used generically to refer to all C# questions, C++ should be used generically to refer to all things C++, and a version-specific tag should be added if that's appropriate.

    Note that old questions that were asked before C++11 came out would no longer make sense if the meaning of the C++ tag changed with the times.

  • @RobertHarvey but it seems the meaning of the C++ tag has changed, as answers today include C++11 features, where they did not before, in your linked question, version specific tags are used to denote older versions, not to denote the current version

  • As I said, I don't completely agree with the philosophy espoused there. C#-5.0 is a perfectly valid tag, used in the manner I described above. It also happens to be the current version. If a C++ question asks about C++14 specific features, I think the question should have both tags.

  • @RobertHarvey - editted question and I expect use of the C++14 tag soon (once it is created)

    @GlennTeitelbaum Robert made the point very well and I think there is a pretty site-wide consensus about it (only version with version tags if you're confined to a specific version). Personally, when dealing with versions in transition I try to offer an 'old' (C++03 in this case) answer and a new (C++11 in this case) answer - I'd also go on answers with an "older" answer and suggest a new version (in an answer or a comment) one if it's considerably better.

  • Can you clarify what you mean when you say that the C++11 tag should be "retired?" All version-specific tags should state (or imply) "please use this tag only when discussing issues unique to this version."

    Okay, let me try to tl;dr this: "C++11 is common enough that people want to begin assuming C++11 when answering. There's wording in the tags that dissuades this. Should the wording be updated, and what should the wording be updated to?" Is that about right?

    This question should be migrated to MSO.
