The usual answer from admin/mods is that a section is made when there is enough demand. I've noticed that C/C++ questions seem to get asked in C# section, so maybe it just needs renaming to C/C++/C#?
Don't forget about Objective C . Actually a Mobile Development SubForum will be nice.. for iOS, Android and...and.. ... hmm maybe not .. ok fine .. and windows.. This sub forum can include the usual "programming stuff', maybe some tips on how to promote your apps, or even how to make money out of your apps ( In Store Purchase , or in-app Ads, etc..), App reviews, etc..
