Until now there have been four standardized versions of C++: C++98, C++03, C++11, and C++14. And the versions have been consistently named (to be precise, "nicknamed") as "C++YY", where YY are the last two digits of the year in which that ISO standard was adopted. Note: C++03 was a very minor change (sort of a "bug fix"), so people sometime refer to C++11 as direct successor of C++98. Also in the interim (2007) there was C++-TR1 ("ISO/IEC TR 19768:2007") which was not a formal standard per se, but instead a technical report specifying bunch of standard library extensions (which were formally included in C++11) For sake of completeness: The format C++YY is the one which is commonly used almost everywhere, but the official language name follow ISO's convention. Here is a mapping: C++98: "ISO/IEC 14882:1998 Programming languages C++" C++03: "ISO/IEC 14882:2003 Programming languages C++" C++11: "ISO/IEC 14882:2011 Programming Language C++" C++14: "ISO/IEC 14882:2014 Programming Language C++" There are also language classifier like (E), (F), etc present at the end (e.g., "ISO/IEC 14882:2014(E) Programming Language C++"). I am not sure if the official standard is fixed in a particular language, or are all the different language translations equally authoritative (I suspect the latter, but it's just a guess).
