Computer Programming Practice Tests

These Grade 10 Additional Subjects practice tests introduce algorithms, variables, data types, input and output, conditionals, loops, functions, collections, debugging, testing, efficiency, cybersecurity, privacy, accessibility, and ethical programming.

Skills covered

  • Explaining algorithms, variables, data types, syntax, input, output, comments, abstraction, and operators
  • Tracing conditionals, for loops, while loops, Boolean expressions, nesting, and stopping conditions
  • Using functions, parameters, arguments, return values, lists, indexes, dictionaries, strings, and scope
  • Distinguishing syntax, runtime, and logic errors and applying testing, decomposition, pseudocode, readability, and efficiency
  • Understanding personal data, encryption, authentication, authorization, algorithmic bias, accessibility, open-source software, and phishing

How to use these practice tests

Trace the program one step at a time. Identify the data type and control structure, then check the expected output, edge cases, and security or ethical effects when the question involves real users.

1. QuestionMultiple choice

What is a syntax error?

Please select an answer first.

Correct answer: A

The correct answer is An error caused by code that violates the language's writing rules.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Syntax errors prevent a program from being parsed or compiled because the code is not written in valid form.
  3. Check the conclusion: The correct answer is An error caused by code that violates the language's writing rules.

Syntax errors prevent a program from being parsed or compiled because the code is not written in valid form.

2. QuestionMultiple choice

What is a runtime error?

Please select an answer first.

Correct answer: B

The correct answer is An error that occurs while a program is executing.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Runtime errors occur during execution, such as dividing by zero or accessing an invalid resource.
  3. Check the conclusion: The correct answer is An error that occurs while a program is executing.

Runtime errors occur during execution, such as dividing by zero or accessing an invalid resource.

3. QuestionMultiple choice

What is a logic error?

Please select an answer first.

Correct answer: C

The correct answer is A flaw that makes a program produce an incorrect result even though it runs.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Logic errors are incorrect decisions or calculations in an otherwise executable program.
  3. Check the conclusion: The correct answer is A flaw that makes a program produce an incorrect result even though it runs.

Logic errors are incorrect decisions or calculations in an otherwise executable program.

4. QuestionMultiple choice

What is debugging?

Please select an answer first.

Correct answer: D

The correct answer is Finding, isolating, and fixing problems in a program.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Debugging uses observation, testing, tracing, and code changes to locate and correct errors.
  3. Check the conclusion: The correct answer is Finding, isolating, and fixing problems in a program.

Debugging uses observation, testing, tracing, and code changes to locate and correct errors.

5. QuestionMultiple choice

Why are test cases useful?

Please select an answer first.

Correct answer: A

The correct answer is They provide planned inputs and expected outputs for checking behavior..

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Test cases make program behavior measurable and help reveal failures across normal, boundary, and unusual inputs.
  3. Check the conclusion: The correct answer is They provide planned inputs and expected outputs for checking behavior..

Test cases make program behavior measurable and help reveal failures across normal, boundary, and unusual inputs.

6. QuestionMultiple choice

What is decomposition?

Please select an answer first.

Correct answer: B

The correct answer is Breaking a complex problem into smaller, manageable parts.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Decomposition makes a problem easier to understand, implement, test, and maintain.
  3. Check the conclusion: The correct answer is Breaking a complex problem into smaller, manageable parts.

Decomposition makes a problem easier to understand, implement, test, and maintain.

7. QuestionMultiple choice

What is pseudocode?

Please select an answer first.

Correct answer: C

The correct answer is A plain-language outline of an algorithm.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
  2. Trace the logic: Pseudocode describes logic without requiring the exact syntax of a programming language.
  3. Check the conclusion: The correct answer is A plain-language outline of an algorithm.

Pseudocode describes logic without requiring the exact syntax of a programming language.

8. QuestionMultiple choice

What does algorithmic efficiency describe?

Please select an answer first.
