This code is like a puzzle, but the solution is just a click away. I'm going to use my trusty debugger to figure this out.

Wait, did we forget to free the memory we allocated? I hope the examiner doesn't deduct points for that. Memory leaks are the bane of every programmer's existence.

Haha, I bet the person who wrote this question is a real sadist. They're probably sitting back and laughing as they watch us struggle with this one.

Wow, this is a classic pointer question! I remember struggling with these in my exam. Good thing I brushed up on my dynamic memory allocation before taking this test.

User 2: That's correct! The code allocates memory for an array of 2 integers and assigns values 0 and 1 to the elements. Then it prints the value at index 1, which is 1.
