Understanding Scratch While Loops

Front

In Scratch programming, what is the primary purpose of a loop control variable in a while loop?

Back

To determine the number of times the loop will execute

Which of the following best describes how a loop control variable is typically used in a while loop in Scratch? It is used to store user input, It is increased or decreased to eventually meet a condition that stops the loop, It is used to display output on the screen, It is used to reset the program

Back

It is increased or decreased to eventually meet a condition that stops the loop

Front

Consider a while loop in Scratch that uses a loop control variable named "counter". After each repetition of the loop, "counter" is increased by 1. If the loop is supposed to run 5 times, what should be the initial value of "counter" and the condition to stop the loop? Initial value: 0, Condition: counter < 5; Initial value: 1, Condition: counter < 5; Initial value: 5, Condition: counter > 0; Initial value: 0, Condition: counter > 5

Back

Initial value: 0, Condition: counter < 5

In a Scratch program, a while loop is controlled by a variable "x" that starts at 10 and decreases by 1 each iteration. What condition should be used to stop the loop after it has run 10 times? Options: x > 0, x < 0, x == 0, x >= 10

Back

x > 0

If the loop control variable in a Scratch while loop is not updated correctly, what is the most likely outcome?

Back

The loop will run indefinitely (infinite loop)
