alt Hacker NewsI have always hated this crap; the fact that I'm not 100% sure the result of this indicates that maybe the ++ operator (pre or postfix) is something that should be avoided?
I don't do a lot of C anymore, but even when I did, I always would do increments on separate lines, and I would do a +=1, or just a = a + 1. I never noticed a performance degradation, and I also don't think my code was harder to read. In fact I think it was easier since I think the semantics were less ambiguous.
I also started doing this. I feel that "b = expr(a); a++;" expresses what I mean better than "b = expr(a++)": store expr(a) in b, then store a+1 in a. Any good compiler will optimize the same.
After separating a++ onto its own line, replacing a++ with a+=1 or a=a+1 comes down to personal taste in syntax sugar. I vote for a+=1.
