Question 1 · 1 mark · Difficulty 1/3

Which of the following is the correct assignment statement syntax in pseudocode as defined by Cambridge IGCSE 0478?

  1. total := price + tax
  2. total = = price + tax
  3. total ← price + tax
  4. total == price + tax
Show answer & explanation
✓ Answer: Ctotal ← price + tax
In Cambridge IGCSE 0478 pseudocode, the assignment operator is ← (left arrow), meaning 'store the value on the right into the variable on the left'. Option A uses == which is a comparison operator. Option C is invalid syntax. Option D uses := which is used in some other languages (e.g. Pascal) but not in Cambridge IGCSE pseudocode.
Question 2 · 1 mark · Difficulty 1/3

Which logical operator returns TRUE only when both of its operands are TRUE?

  1. XOR
  2. AND
  3. NOT
  4. OR
Show answer & explanation
✓ Answer: BAND
The AND operator returns TRUE only when both operands are TRUE; if either operand is FALSE, the result is FALSE. OR returns TRUE when at least one operand is TRUE. NOT inverts a single Boolean value. XOR is not part of the Cambridge IGCSE 0478 core pseudocode operator set and returns TRUE only when operands differ.

CIE IGCSE Computer Science: Programming concepts: input/output, assignment and arithmetic, comparison and logical operators FAQ

How many CIE IGCSE Computer Science questions on Programming concepts: input/output, assignment and arithmetic, comparison and logical operators are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Programming concepts: input/output, assignment and arithmetic, comparison and logical operators 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: input/output, assignment and arithmetic, comparison and logical operators 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: input/output, assignment and arithmetic, comparison and logical operators 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: input/output, assignment and arithmetic, comparison and logical operators typically tested on CIE IGCSE Computer Science papers?
Programming concepts: input/output, assignment and arithmetic, comparison and logical operators 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.
