Wait, wait, wait... so you're telling me that 'empty' doesn't actually make things... well, empty? Looks like the joke's on us, folks!

User 3: So the program will output 'I am not empty 10 10'.

User 2: I guess it's more about checking if it's empty rather than making it empty.

Yeah, 'empty' doesn't actually make things empty.

This question is a real head-scratcher! I'm going with D though, because I'm pretty sure the empty() function doesn't change the size of the containers.

I'm not sure, but I think the correct answer is D) program outputs: I am not empty 10 10 because the vector and deque are filled with 10 elements.

I agree with Erinn, the vector and deque are initialized with values so they are not empty.

I'm a bit rusty on my C++ containers, but I think D has to be the right answer. The empty() function doesn't affect the size, it just checks if the container is empty or not.

Haha, looks like someone's trying to trick us with a classic 'empty' vs 'size' confusion. D is the winner here!

The correct answer is D. The program outputs 'I am not empty 10 10' because the vector and deque are both initialized with the array 't' and the empty() function does not change the size of the containers.

That makes sense, the containers are initialized with the array 't'.
