In Scratch, which loop would you use to repeat a set of blocks a fixed number of times?

• A. Forever loop
• B. Repeat n times
• C. Repeat until
• D. Repeat while

Answer: (B)

To run a block sequence a fixed number of times in Scratch, use the repeat n times loop. You set the exact number of iterations (n), and the blocks inside run that many times—no more, no less. This is exactly what you want when you know the exact count you need, like making a sprite say something five times or move a certain distance in five steps. The forever loop keeps repeating endlessly, so it isn’t fixed to a set count. The repeat until loop runs until a condition becomes true, so how many times it repeats depends on when that condition happens. The repeat while loop continues as long as a condition is true, which means the number of repetitions depends on how the condition changes.
