Post incs not happening until after th ';' would be a reasonable way to
implement it. BUT, K&R did not specify that. The post incs can be done
any time after the value of N is fetched for evaluation until after the
';'. That is left as a decision for the compiler author to do in whatever
way they want to implement it.
Also, should we assume that N will be incremented twice?
