What Is A Cv Qualifier C++

with the word const? –Raymond Chen Nov 6 '13 at 13:08 1 possible duplicate of Why there is no concept of "const-correctness" for class's static member functions? –Raymond Chen Nov 6 '13 at 13:11 1 const on static function could be used to prevent the static function from changing the state of the class. Then why the error or so the standard? –Sahil Sareen Nov 6 '13 at 14:23 You seem to be changing your question. First you ask "What does it mean?" Now you're asking "Why doesn't it mean what I want it to mean?" Questions about why a language is designed a certain way don't really fit this site since they aren't practical. (Whether the language is designed the way you like doesn't alter the fact that you have to program to the language you have, not the language you wish you had.) At any rate, there is some discussion of the rationale in the linked duplicate. –Raymond Chen Nov 6 '13 at 14:28 add a comment| 5 Answers 5 active oldest votes up vote 27 down vote accepted Worth quoting the standard here 9.4.1 Static member functions 2) [ Note: A static member function does not have a this pointer (9.3.2). —end note ] A static member function shall not be virtual.

If a member function doesn't use any of the member variables should it be static.

That is interesting. Thoughts? –baash05 Mar 30 '10 at 1:52 Why is this a community Wiki? –Uri Mar 30 '10 at 2:18 Because there isn't really an answer. (beyond the one my mate proposed) and I don't like having questions rated. In the past a technical|specific|answerable questions has lost me points. I don't give a hoot about my personal points, but I felt personally invalidated. If I ask a T|S|A, I lose. If I ask a "what is your fav...", I gain.
