Hi Paul,
Just a tiny but hopefully
useful thought I had about the question.
As it stands, both logical && and bitwise & will produce the same result.
If i++ were tested for equality with an int other than 0
it would bring the second concept in the explanation into play.

In this particular case, yes.

Not sure what you mean. Can you write it in code so that it is clear what you mean?

Hmmm, I'm splitting hairs really and my confidence in the idea is waning but...
my thought was to try to add something the question by having the first expression evaluate as false like:
Code: Select all
int i = 0;
int j = 1;
if ((i++ == 1) & (j++ == 2)) {
i = 12;
}
(to test if the answerer spots the single & operator)

You got it right. That would make the question tougher. I think that is covered in some other question though. Not every question needs to hit all the gotchas
