IGCSE Computer Science 0478: Iteration, totalling and counting
Students learn to repeat code with FOR, WHILE and REPEAT…UNTIL loops, choose the right loop type, and use loops to total, count, average and validate input.
One content description from the full IGCSE Computer Science 0478 — 8.1b Sequence, Selection and Iteration journey. All 12 modules below are in that journey too, with the same content — add just these to a class, or the whole strand.
