Haha, this question is a real brain-teaser! I'm going to go with option B, int(3), because that's the only answer that seems somewhat logical.

Wait, what? This question is as clear as mud. I'll just go with option E, Array, because that's the only answer that makes sense to me.

I think the output will be int(3) because the current function returns the current element in an array.

I'm not sure about this one. The code looks a bit weird, but I'm going to go with option D, NULL, just to be safe.

No way, the output is clearly int(3)! The while loop just iterates through the array, and current() will return the last element.

Hmm, I think the output will be bool(false), since the while loop has already exhausted the array and current() will return the last element's value.

I agree with you, the output should be bool(false) as current() will return false after the while loop.
