What is the primary purpose of a function in Karel programming?

• To teach Karel a new word or command.

• To make Karel move forward.

• To define a variable.

• To display text on the screen.

Which of the following is NOT a reason to use functions in programming?

• To break a program into smaller, manageable parts.

• To make the program easier to understand.

• To avoid repeating code.

• To increase the program's execution speed.

How do functions contribute to collaborative coding projects?

• They automatically fix errors in other programmers' code.

• They make it easier for others to understand your code.

• They prevent multiple programmers from working on the same file.

• They reduce the need for comments in the code.

What is the fundamental concept behind programming, as explained in the context of functions?

• Solving complex mathematical equations.

• Teaching the computer to perform new tasks.

• Designing graphical user interfaces.

• Storing large amounts of data.

What keyword is used to begin the definition of a function in Karel programming?

• start

• function

• def

• create

A function name should ideally start with what type of word?

• A noun.

• An adjective.

• An action verb.

• A number.

Which of the following is a recommended practice for naming functions?

• Start the name with a number.

• Use spaces between words in the name.

• Use all lowercase letters and separate words with underscores (snake_case).

• Make the name as short as possible, even if it's not descriptive.

What is the difference between "defining a function" and "calling a function"?

• Defining a function executes the code, while calling it only declares it.

• Defining a function teaches a new action, while calling it causes that action to happen.

• Defining a function is for simple tasks, calling is for complex tasks.

• Defining a function is done by the computer, calling is done by the programmer.

If you define a function named turn_around() to make Karel turn 180 degrees, what must you do for Karel to actually turn around?

• Redefine the function multiple times.

• Call the turn_around() function.

• Delete the function definition.

• Change the function's name.

In most programming languages like Python, what is the necessary order for a function's definition and its call within the code?

• The function call must appear before its definition.

• The function definition must appear before its call.

• The order does not matter.

• Functions can only be called from within other functions.
