Activity B - Short Answer Practice (2-4 marks each)

(Section B format - active recall)

1. Explain one reason why meaningful naming conventions improve maintainability.

2. Describe one difference between a useful comment and a poor comment.

3. Explain why boundary values are important in testing.

4. Distinguish between syntax, runtime and logic errors.

5. Explain one advantage of using a breakpoint.

6. Describe one situation where a debugging statement could help.

Activity C - Scenario Application (3-6 marks each)

(Section C style - applied retrieval)

Scenario 1 - Age checker testing

A program only accepts an age between 15 and 17 inclusive.

Tasks:

  1. Suggest two appropriate boundary test values.
  2. Explain why each is useful.
  3. State what the expected result should be for each.

Scenario 2 - Poorly documented code

A student writes the following:

int x = 3;
double y = 7.50;
double z = x * y;
Console.WriteLine(z);

Tasks:

  1. Explain one naming problem.
  2. Explain one comment or documentation improvement that could help.
  3. Describe one way this code could be made easier to maintain.

Activity D - Extended Response (6-8 marks)

(Analytical / evaluation task)

Prompt:

Discuss why readable code, testing and debugging are all necessary parts of creating a quality software solution.

In your response, refer to:

  • naming conventions
  • internal documentation
  • test data and expected results
  • at least one debugging technique
