Question 1 · 1 mark · Difficulty 1/3

A 1D array called Scores is declared to store 10 integer values. Which of the following correctly accesses the fifth element in pseudocode following Cambridge IGCSE conventions?

  1. Scores{4}
  2. Scores(5)
  3. Scores[4]
  4. Scores[5]
Show answer & explanation
✓ Answer: CScores[4]
Cambridge IGCSE pseudocode uses zero-based indexing by default, so the fifth element is at index 4, accessed as Scores[4]. Option A accesses the sixth element due to zero-based indexing. Option C uses round brackets which are not the correct array notation in Cambridge pseudocode. Option D uses curly braces which are not valid array notation.
Question 2 · 1 mark · Difficulty 1/3

A 2D array called Grid is declared as Grid[3][4]. How many elements does this array store in total?

  1. 12 elements
  2. 16 elements
  3. 7 elements
  4. 3 elements
Show answer & explanation
✓ Answer: A12 elements
A 2D array declared as Grid[3][4] has 3 rows and 4 columns, giving 3 × 4 = 12 elements in total. Option A incorrectly adds the dimensions (3 + 4 = 7). Option B takes only the first dimension. Option D incorrectly squares one dimension (4 × 4 = 16).

CIE IGCSE Computer Science: Programming concepts: arrays (1D and 2D) — declaration, access and manipulation FAQ

How many CIE IGCSE Computer Science questions on Programming concepts: arrays (1D and 2D) — declaration, access and manipulation are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Programming concepts: arrays (1D and 2D) — declaration, access and manipulation for CIE IGCSE Computer Science, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CIE IGCSE students preparing for Computer Science?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Programming concepts: arrays (1D and 2D) — declaration, access and manipulation practice with other Computer Science topics or even switch to a totally different CIE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Programming concepts: arrays (1D and 2D) — declaration, access and manipulation questions aligned to the official CIE IGCSE Computer Science syllabus?
Every question is written against the published CIE IGCSE Computer Science specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CIE.
How is Programming concepts: arrays (1D and 2D) — declaration, access and manipulation typically tested on CIE IGCSE Computer Science papers?
Programming concepts: arrays (1D and 2D) — declaration, access and manipulation appears across multiple question types on real CIE IGCSE Computer Science papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
