I'm going with D) It prints: to. Surely, the swap() function will only affect the first two elements, and the rest will be ignored, right?

Haha, this question is a classic! The answer is clearly B) It prints: toHow. Swapping the elements of a string array is like a magic trick, isn't it?

I think the answer is A) It prints: Hoto. The swap() function will swap the elements of the string array, but the output will be concatenated.

The correct answer is B) It prints: toHow. The swap() function will swap the elements of the string array, so the output will be reversed.
