for loop

--feedback--

This two-word phrase refers to the loop that is used when you know how many times it should run.


while loop

--feedback--

This two-word phrase refers to the loop that is used when the number of repetitions depends on a condition.

--explanation--

A for loop is useful when you know how many times the loop should run. For example:

  • A for loop is useful for going through a list. - You can use it to check each item in a list.

  • The for loop stops when it reaches the last item. - The loop ends when there are no more items.

A while loop is better when the number of repetitions depends on a condition. For example:

  • A while loop runs until a condition is false. - The loop continues as long as the rule is true.

  • Be careful, a while loop can run forever! - If you don't stop it, the loop won't end.
