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 does an if statement do?

Please select an answer first.

Correct answer: A

The correct answer is It runs code only when a condition is true..

  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: A conditional statement chooses whether to execute a block based on a Boolean condition.
  3. Check the conclusion: The correct answer is It runs code only when a condition is true..

A conditional statement chooses whether to execute a block based on a Boolean condition.

2. QuestionMultiple choice

What is an else clause used for?

Please select an answer first.

Correct answer: B

The correct answer is It provides code to run when the preceding condition is false..

  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: The else branch handles the alternative case when an if condition is not satisfied.
  3. Check the conclusion: The correct answer is It provides code to run when the preceding condition is false..

The else branch handles the alternative case when an if condition is not satisfied.

3. QuestionMultiple choice

What is a loop?

Please select an answer first.

Correct answer: C

The correct answer is A structure that repeats a block of code.

  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: Loops automate repeated work and continue according to a condition or a collection of items.
  3. Check the conclusion: The correct answer is A structure that repeats a block of code.

Loops automate repeated work and continue according to a condition or a collection of items.

4. QuestionMultiple choice

When is a for loop commonly useful?

Please select an answer first.

Correct answer: D

The correct answer is When repeating over a known sequence or range.

  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: A for loop is useful for processing each item in a sequence or each value in a defined range.
  3. Check the conclusion: The correct answer is When repeating over a known sequence or range.

A for loop is useful for processing each item in a sequence or each value in a defined range.

5. QuestionMultiple choice

When is a while loop commonly useful?

Please select an answer first.

Correct answer: A

The correct answer is When repetition should continue while a condition remains true.

  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: A while loop checks a condition and repeats as long as the condition is true.
  3. Check the conclusion: The correct answer is When repetition should continue while a condition remains true.

A while loop checks a condition and repeats as long as the condition is true.

6. QuestionMultiple choice

What is an infinite loop?

Please select an answer first.

Correct answer: B

The correct answer is A loop that never reaches a condition that stops it.

  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: An infinite loop can occur when the stopping condition is never met or the loop variable is not updated correctly.
  3. Check the conclusion: The correct answer is A loop that never reaches a condition that stops it.

An infinite loop can occur when the stopping condition is never met or the loop variable is not updated correctly.

7. QuestionMultiple choice

What is nesting in programming?

Please select an answer first.

Correct answer: C

The correct answer is Placing one control structure inside another.

  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: Nested conditionals and loops allow one decision or repetition to operate inside another.
  3. Check the conclusion: The correct answer is Placing one control structure inside another.

Nested conditionals and loops allow one decision or repetition to operate inside another.

8. QuestionMultiple choice

What is a Boolean expression?

Please select an answer first.

Correct answer: D

The correct answer is An expression that evaluates to True or False.

  1. Identify the programming concept: Determine whether the question asks about an algorithm, data, control flow, a function, debugging, efficiency, security, or ethics.
