Question 29

What happens when this loop runs?
SET count TO 10
REPEAT WHILE count > 0
  DISPLAY count
  SET count TO count + 1

Accepted Answer

It never ends, because count moves further above 0 on every pass.

Answer

It runs ten times, because count counts down to 0.

Answer

It never runs, because count is already greater than 0.

Answer

It runs once, because the condition is checked only before the first pass.

Question 30

Which statement correctly describes this loop?
SET i TO 1
REPEAT WHILE i < 5
  DISPLAY i

Accepted Answer

It never ends because i is never changed, so i < 5 stays true.

Answer

It displays 1 through 5 once because the condition supplies the counter.

Answer

It stops after one pass because i starts at 1.

Answer

It never runs because i is less than 5.

Question 31

What happens when this loop runs?
SET level TO 1
REPEAT WHILE level < 4
  DISPLAY level
  SET level TO 1

Accepted Answer

It never ends because level is reset to 1, so the condition remains true.

Answer

It displays 1, 2, 3, 4 because level rises each pass.

Answer

It stops after displaying 1 because assigning 1 makes the condition false.

Answer

It never runs because level is not 4.

Question 32

DIV divides and discards any remainder. What happens when this loop runs?
SET n TO 1
REPEAT WHILE n > 0
  DISPLAY n
  SET n TO n DIV 1

Accepted Answer

It never ends because n DIV 1 is still 1, so n stays positive.

Answer

It ends after one pass because n DIV 1 becomes 0.

Answer

It runs twice because integer division removes one from n.

Answer

It never runs because n is equal to 1.

Question 33

What happens when this loop runs?
SET done TO false
REPEAT WHILE NOT done
  DISPLAY "Working"

Accepted Answer

It never ends because done stays false, so NOT done stays true.

Answer

It ends after one pass because NOT false becomes false.

Answer

It never runs because done is false.

Answer

It ends when "Working" is displayed.

Question 34

Which statement correctly describes this loop?
SET temperature TO 0
REPEAT WHILE temperature <= 20
  DISPLAY temperature
  SET temperature TO temperature - 2

Accepted Answer

It never ends because temperature decreases and remains less than or equal to 20.

Answer

It stops at 20 because subtracting 2 moves temperature toward 20.

Answer

It runs eleven times because 0 through 20 has eleven even values.

Answer

It never runs because temperature starts at 0.
