Pointer
Pointer is a DSA topic. In plain words you use it for a short Pointer example in a short dry-run on paper. Don’t start with a slogan — start with that picture.
Smallest example: the smallest Pointer example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Pointer.
From the example next to this theory — Pointer: dry-run [4, 1, 3].
Trap — only saying “Pointer” with no example. Fix that before you talk about advanced DSA.
Viva — what is Pointer? Then show the smallest Pointer example you can type. Then name the trap.
Exam tip
