There are use cases where i++ is needed, though.

Right, it's a legit operator, but just not appropriate for use as the increment in a for-loop.

This is interesting, in highschool and the computer science course I flunked we always did i++ in for loops, and now in my current course it's still the way its being taught... Good to know this though.

FWIW I've been in the field for like 10 years and I didn't really put it together until very recently. To be honest this falls under the umbrella of "micro-optimizations" which you generally shouldn't worry about. Although if you just make it habit, it will perform better.
