I feel like I’ve seen a question like this before, and I think it was about concurrent states not necessarily needing boundary transitions. Could that be option C?
I remember learning about this in class. The tricky part is distinguishing between composite and concurrent states. I'm pretty sure B and C are the correct statements, but I'll double-check my notes just to be sure.
Okay, I think I've got this. Boundary transitions are used for composite and concurrent states, but the key difference is that composite states can use them optionally, while concurrent states must use them. And when a transition crosses state boundaries, the exit actions are always executed. I'm feeling good about B and C as the answers.
Hmm, I'm a bit confused on this one. I know transitions and state boundaries are important, but I'm not sure about the specifics of when entry/exit actions are executed. I'll have to think this through carefully.
I'm pretty sure the answer is B and C, but I'm not totally confident about it. I'll need to review the concepts of composite and concurrent states again.
