• However many times you like

Which of the following is a benefit of using functions in programming?

• Breaking down the program into smaller parts

• 
  Avoiding code repetition

• 
  Improving program readability

• All of the above

Why is it recommended to use functions in programming? (Select all that apply)

• 
  To divide the program into bigger, modular sections

• 
  To prevent redundant code

• 
  To enhance the overall clarity and comprehensibility of the program

• 
  All of the above

Which characteristic distinguishes top-down design from other design approaches in programming?

• 
  It emphasizes breaking down the problem into smaller, more manageable pieces.

• 
  It focuses on creating visually appealing designs for web pages.

• 
  It prioritizes writing individual commands as the first step in programming.

• It primarily relies on loops and classes to structure the program's execution.

When applying top-down design, what is the recommended approach to tackling a programming problem?

• Begin by writing individual commands and then organize them into a coherent program.

• 
  Design graphical elements for web pages before writing the underlying code.

• Start by identifying the major problem and then decompose it into sub-problems.

• Utilize loops and classes to handle complex data structures.

What is the primary benefit of using code comments in your program?

• It helps Karel learn new words and commands

• It allows you to send secret messages to other programmers

• It improves the readability and understanding of your code for other developers

• It provides a space to write personal thoughts and reflections

What is the recommended approach for adding code comments to your program?

• Add comments randomly throughout your code without any specific purpose

• 
  Add comments strategically to clarify your code's logic and intentions

• 
  Use comments solely for personal reminders and to-do lists

• Avoid using comments altogether as they are unnecessary
