The five most significant revisions of the C++ standard are
C++98 (1998), C++03 (2003) and C++11 (2011), C++14 (2014) and C++17 (2017)
The next iteration is currently expected in 2020. Of course,
it can be a challenging task for software engineers,
compiler writers and lecturers (!) to keep track of all the
revisions that appear in each major version of the standard
