##some c++QQ topics I took up since Apr17

Combine with https://bintanvictor.wordpress.com/wp-admin/post.php?post=24064&action=edit ? no need… Don’t spend too much time! I keep this list only as motivation and reward, but I don’t want a long list. I want heavy-hitters only, non-exhaustive.

Note “Take-up/Conquest” mean … I now feel as competent as my interviewers on that topic.
