A glimpse of undefined behavior in C

I think users of for/while loops will disagree. Don't forget that =, += , ... can all be abused in the same way.

    (int i=0;i<10;i++)

would count as three lines for purposes of that rule, and the

i++

as one. I could have been more precise, but I thought it would be understood.

The point is, to be on the safe side, don't use ++/-- in any line (in the sense of ;{}-delimited statement) that is also doing something else.

I didn't, and people should use the same safeguards around them, i.e. don't mix them within lines that do other things, "cleverness" or "C golf" be damned.
