You're right, that's what I get for not having written a line of C in what 15 years. Bonus challenge: write
for i in i32::MIN..=i32::MAXin C, that is, iterate over the whole range, start and end inclusive.(I guess the
..=might be where my confusion came from because Rust's..is end-exclusive and thus like<, but also not what you want becausei32::MAX + 1panics).Would you be bold enough to write
if (i++ == INT_MAX) break? The result of the increment is never used, but an increment is being done, at least syntactically, and it overflows, at least theoretically, so maybe (I'm not 100% sure) the compiler could be allowed to break out into song because undefined behaviour allows anything to happen.
