Understanding For Loops

What is the primary purpose of a for loop?

• To define variables

• To handle errors in code

• To repeat code for each item in a collection

• To execute code once

If an array has 10 items, how many times will a for loop iterate over it?

• 5 times

• 10 times

• 15 times

• 20 times

What happens to the loop variable after the for loop ends?

• It retains its last value

• It becomes undefined

• It resets to zero

• It becomes a global variable

In the monkey and bananas example, what does the variable 'b' represent?

• The distance to the next banana

• The total number of bananas

• The index of the last banana

• The current banana being processed

Why is it important to know the scope of a loop variable?

• To make it a constant

• To avoid errors in the loop

• To use it outside the loop

• To change its value globally

In the turtles and bananas challenge, what determines the number of loop iterations?

• The number of variables

• The number of bananas

• The number of turtles

• The number of steps

What is the benefit of using a loop variable like 't' in the turtles example?

• It makes the code less readable

• It reduces the number of arrays

• It increases the loop count

• It allows for flexible iteration

How does the loop variable 't' change during each iteration in the turtles example?

• It becomes a new turtle

• It resets to zero

• It stays the same

• It becomes a new banana

What should you do if you want to loop over a different array in the turtles challenge?

• Change the loop variable

• Remove some bananas

• Change the array name in the loop

• Add more turtles

What is the next step after reviewing for loops in the video?

• Read a book

• Take a break

• Watch another video

• Apply the knowledge
