Linked List - M-Choice Question

[yogi_bear_79]

Assume a linked list of nodes which have an info data member and a
next data member. Suppose a pointer called cursor points to a node in
the middle of the linked list. To move ptr to the next node use:


ptr=next;
next->ptr;
ptr->next;
ptr=ptr->next;
none of the above.

I want to anwser none of the above as i feel it should be cursor-

next; But I could also anwser ptr->next; if I disregard the info

leading up to last sentacne which is the actual question (To move ptr
to the next node use. is this a trick question, or am i reading to
much into it?

My guess is that is not meant to be a trick question, just a question posed
by somene who has difficulty saying what he means. "Suppose a pointer
called cursor... " There is no such pointer in the code. Did he mean "To
change ptr to point to the next node?" That isn't what he says, is it?

If we assume that it is not a trick question the correct answer is 4
(ptr=ptr->next). If it is a trick question (which I doubt) then the
correct answer is 5 (none of the above), just like you said.

My guess is that its a typographical error, and that they intented "ptr"
and "cursor" to be the same thing. I'd suggest trying to get
clarification if possible.

I'd imagine it is not supposed to be a trick. Asking for clarification
has proved pointless. This is the second of four tests. I asked for
clarification after I took the first one, and received nada. The tests
are extremely badly written. They are not in the text book.
