Which function will allow Karel to spin in circle?

• 
• 
•

What is a reason we use functions?

• Break down our program into smaller parts.

• Because it is more complex.

• It looks cool and helps the fight against martians!

• Functions are basically Algebra and programmers like Algebra.

What is another reason we use functions?

• To help make things in programming more complex.

• to repeat code more frequently and make it harder to others to know what we are doing.

• To avoid repeating code and make it more readable.

• To help fight against galactic invaders and keep cats out of Karel's world.

What is top down design?

• Top down design is a way of designing your program by starting with the biggest problem and breaking it down into smaller and smaller pieces that are easier to solve.

• Top down design is a way that you can create designs on a computer to put on a web page

• Top down design is a way of designing your programs starting with the individual commands first

• Top down design is a way to use loops and classes to decompose the problem

In the following code snippet, how many times is the turnRight function called and how many times is it defined?

• Called 1 time, defined 1 time

• Called 1 time, defined 3 times

• Called 3 times, defined 1 time

• Called 3 times, defined 3 times

What is a code comment?

• A way to teach Karel a new word

• A way to give notes to the reader to explain what your code is doing

• A message to your teacher in code

• A place to write whatever you want in your code

You need to write a program where Karel will take a ball if there is a ball present, otherwise Karel should put down a ball.

Which control structure do you need to use?

• For Loop

• While Loop

• If Statement

• If/Else Statement

• None of these

You need to write a program that has Karel take all the tennis balls where Karel is standing if there are any there.

Karel should end up with no tennis balls on that spot.

Which control structure do you need to use?

• For Loop

• While Loop

• If Statement

• If/Else Statement

• None of these
