Which of the following best describes the purpose of syntax analysis during compilation?

Q: How do I try a free OCR Computer Science question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live OCR GCSE Computer Science bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for OCR Computer Science students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Computer Science questions aligned to the OCR GCSE syllabus?

Every question is written against the published OCR GCSE Computer Science syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real OCR past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Which of the following best describes the purpose of syntax analysis during compilation?

Accepted Answer

Checking that the program's grammar rules are correctly followed — Syntax analysis (parsing) checks that the sequence of tokens conforms to the grammar rules of the programming language, for example that every open bracket has a matching close bracket. Converting characters to tokens is lexical analysis. Checking variable types is semantic analysis. Producing machine code is code generation.

Answer

Checking that the program's grammar rules are correctly followed

Answer

Translating the intermediate code into machine code instructions

Answer

Converting source code characters into a stream of tokens

Answer

Verifying that variable types are used consistently throughout the code
