short circuit evaluation

[jpn at teddy.UUCP]

Why is there so much misinformation in this group?!?!  I wish people who
don't know what they are talking about would not post here!

>I can find no promise in K&R that bitwise expressions are not short
>circuited even in the presence of side effects.

60 seconds with my copy of K&R yeilds this (Appendix A):

  "The & operator is associative and expressions involving & may be rearranged"

  "Unlike &, && guarantees left-to-right evaluation; moreover, the second
   operand is not evaluated if the first operand is zero"

>In any case, I would advise not counting on full evaluation (of bitwise). 

True, it is not explitly stated that & and | are not short circuited.  It
also doesn't explicitly say that + and * are not short circuited!  However
&& and || are EXPLICITY defined as having short circuit behavier, no other
operators are described this way, so it is safe to assume that all other
operators do NOT short-circuit.
