Question

Which entry can use the pointer in the linked list?

(a) first entry

(b) last entry

(c) second entry

(d) third entry

This question was addressed to me in class test.

My question is from Buffer Exchange topic in division Buffering and other Data Structures of Embedded Systems

Answer 1

The correct choice is (a) first entry

For explanation I would say: The first entry of the single linked list will use the pointer entry to point the location of the second entry and so on. The last entry will have a special value that indicates that the entry is the last one.
