Wait, are we sure about D? I thought it had to be initialized!

D isn't true, you can declare without initializing.

I feel like option D is tricky. I know you can declare an array without initializing it, but it might be better to initialize it right away.

For option C, I believe tab[9] is indeed the last element, but I might be mixing it up with other examples we did in class.

I'm not so sure about option B; I remember something about indexing starting at 0, so wouldn't tab[1] be the second element?

I think option A is definitely correct since the array is declared to hold 10 elements.

Okay, I've got this. The first statement is correct - the array can store 10 elements. The second statement is wrong, the first element is at index 0, not 1. The third statement is correct, tab[9] is the last element. And the fourth statement is false, we don't have to initialize the array on declaration.

Hmm, I'm a bit unsure about the last statement. Do we really need to initialize the array when we declare it? I'll have to think that one through.

This looks like a straightforward question about array basics. I'll start by carefully reading through each statement and thinking about whether it's correct or not.

I'm a little confused by the array indexing. Is it 0-based or 1-based? I better double-check that before answering.
