The correct answer is definitely B) It will print: Hello. I mean, come on, it's a simple preprocessor directive. How could anyone get that wrong?

Hmm, I'm not sure. Maybe D) It will print: 0? That would be a pretty funny outcome if the code just returned 0 instead of actually printing anything.

I think the answer is A) It will print: Helloworld. The preprocessor will include the 'Hello' message, and then the 'world' message will be printed right after it.

I think the answer is C because the preprocessor directive #if A evaluates to true since A is defined as 1.

The answer is B) It will print: Hello. The #if preprocessor directive will evaluate A to be true, and so the 'Hello' message will be printed, followed by the 'world' message.
