Module Assessment

1.

What is the primary problem with deeply nested conditional statements?

They execute slower than simple conditionals.

They reduce code readability and increase cognitive load, making the code harder to understand and maintain.

They use more memory than flattened conditional logic.

2.

Which metric is commonly used to measure the complexity of conditional logic in code?

Lines of code (LOC).

Cyclomatic complexity.

Function count.

3.

What is the primary benefit of using guard clauses in conditional logic?

They eliminate the need for any conditional statements.

They flatten nesting by handling exceptional conditions early and allowing the main logic to focus on the 'happy path.'

They improve performance by skipping unnecessary checks.

4.

What is the key difference between GitHub Copilot's Ask mode and Agent mode?

Ask mode works with C# while Agent mode works with JavaScript.

Ask mode provides explanations and suggestions without directly modifying code, while Agent mode can actually edit files and make changes.

Ask mode is free while Agent mode requires a paid subscription.

5.

When using GitHub Copilot's Ask mode to analyze complex conditionals, what should you do first?

Immediately ask for refactoring suggestions without context.

Select the relevant code and ask Copilot to explain what the method or function is doing.

Delete the complex code and start over with a completely new approach.

6.

What should you do before using GitHub Copilot's Agent mode to refactor complex conditionals?

Create a backup or ensure you're using version control to track changes.

Disable all other extensions in your IDE.

Manually delete all existing conditional statements first.

7.

Which refactoring technique is most effective for replacing long chains of if-else statements that check a single variable against multiple values?

Adding more comments to explain each condition.

Using switch statements or pattern matching to create a cleaner declarative structure.

Converting all conditions to nested ternary operators.

8.

What is the main advantage of extracting complex conditional logic into separate helper methods?

It eliminates the need for any conditional statements.

It improves code readability by giving meaningful names to complex conditions and reduces the cognitive load of the main method.

It automatically optimizes the code for better performance.
