2.3 Quiz on Robust Programming Principles

What is the primary goal of "defensive design" in programming?

• To make code visually appealing.

• To prevent the program from crashing due to unexpected input or conditions.

• To make the code run faster.

• To reduce the number of lines of code.

Which of the following is a good practice for writing maintainable code?

• Using single-letter variable names to save space.

• Writing long blocks of code without comments.

• Using meaningful variable names that clearly indicate their purpose.

• Copying and pasting code instead of using functions.

What is the purpose of testing in software development?

• To prove that the code is always perfect.

• To identify and fix errors or bugs in the code.

• To make the code run faster.

• To reduce the number of lines of code.

Which of the following is an example of a syntax error?

• A program that runs but produces incorrect results.

• A program that crashes due to a division by zero.

• A missing colon in an if statement.

• A program that takes too long to execute.

What is the benefit of using sub-programs (functions or procedures) in programming?

• They make the code run slower.

• They allow for code reuse and better organisation.

• They increase the number of lines of code.

• They make the code harder to understand.

Why is it important to use comments in your code?

• To make the code look more complex.

• To explain the purpose and functionality of the code to others.

• To increase the file size.

• To make the code run faster.

What is a common practice to handle errors in a program?

• Ignore them and hope they go away.

• Use error handling techniques like try-catch blocks.

• Delete the code that causes errors.

• Restart the computer.

Which of the following is a characteristic of robust code?

• It only works under specific conditions.

• It can handle unexpected inputs gracefully.

• It is written in a single line.

• It requires constant maintenance.
