When I was young, I thought I understood C++, because I had been taught it in school. I did not. Having interviewed several recent graduates who thought they knew C++, I believe this is fairly common, particularly among people with advanced degrees in engineering and the sciences. It's very easy, in C++, not to know the scope of one's ignorance.

This is very true. I've seen very ignorant (on c++) people say that they dont find c++ complex at all, but very simple.

Most of the time this only shows the lack of deep knowledge on the language.

You can do the same with someone that says C is easy to master.

Just pick a copy of ANSI C and randomly ask a couple of UB questions.

You have a catalog of about 200 cases to chose from.
