Exactly. Furthermore, in this case we aren't even given enough information to derive a "true" direct answer. What's the architecture? The compiler? Hell, we don't even know the language! Assuming x86, gcc, and C, which is a best case assumption (from the standpoint of easily being able to come upon an answer, and test it) we still don't quite know. What optimization level is being used? Without answers to all of those questions, and likely more, the only possible answer is "if you need to know, you already messed up".
