They survive to the idea that text/date/... are "basic" types in SQL.
Maybe I'm lucky... they could prefer java references with new/equals...;-)
If I take your example about details of && vs AND semantics, while
teaching "programming concepts" I'm not going to discuss the fact that &&
is shortcut by the evaluator, as this is very specific.
I'm not planing my students to know what "i=++i+i++;" could mean.
If I teach about "java/c/c++/java", this may be an issue.
So it depends on the course goal.
Well, I'm happy that so many people have ideas about what to teach and how
to teach it;-)
Have a nice day,
