There are a lot of questions tagged as c questions. Although some of them are relevant for C only (e.g.
void* ptr = malloc(...);) , a lot of them are relevant to C++ as well, at least to its procedural subset.
Is it reasonable to add c++ tag to such questions where the code is valid C++ code and why? Some advantages off the top of my head: less duplicating questions half of which are tagged c, half of which are tagged c++.
Note: I don't pretend to say this necessarily is a good idea - I just want to know what others think about it. I have seen posts with exactly the opposite opinion. The question itself is still relevant - I know other people who aren't sure about it as well, and I've seen such edits on SO myself in the past.
