No way, it's just a pointer to char!

Wait, isn't it also a pointer to a pointer to a pointer?

I agree, it's not a pointer to char* though.

ptr is definitely a pointer to a pointer to char.

I thought C was a possibility too, but I don't recall seeing a triple pointer in our examples. A seems more straightforward.

I practiced a similar question where we had to identify pointer types, and I think A and D are the most likely answers here.

I'm not entirely sure, but I feel like B could be misleading since it says "pointer to char*" instead of "pointer to pointer."

I remember that a double pointer means it's pointing to another pointer, so I think A is correct.

Whoa, pointers to pointers? This is getting a bit complex. I'll have to review my notes on pointer syntax.

Okay, so I need to add a new write-off reason and set it as the default. That makes sense, I should be able to do that.

I'm a bit confused about option C. I feel like an event management program can take on the subscriber role, but isn't it usually just the direct consumers that subscribe?

Okay, let's see. I need to set the verification mode and password for the host account, and then log in as the ldapuser40 user. And I have to download a certificate from a specific URL. Seems doable, but I'll want to double-check my work.

I'm a bit confused about the options here. Should the project manager inform the sponsor that there can't be any changes to the scope, or should they involve the legal department in the negotiation? I'm not sure which one is the best approach.
