I've always done post-increment because 1. it's called C++ not ++C 2. examples usually do it that way but the reality is it doesn't matter in the slightest, except in extremely niche edge cases

It should be called ++C as C++ is actually just C when you evaluate it. C++ is only incremented after the fact. ;-)

even it's name is a bug, lol

For reverse loops C has the --> ("downto") operator. So if you want to count from i to zero you do. while (i --> 0) { printf("%d", i); } or do you do? for(size_t i = count-1, i < count; i--) or for(int i = count-1, i >= 0, i--)

It got big from the correctness culture in C++ originally though right? Something something evaluation order resulting in unnecessary copies or temps or somesuch

Literally doesn't matter. Drop it into godbolt some time to see for yourself.

Im on my phone, but from memory that was always know it was more a matter of whether you had a non-trivial copy constructor or something like that
