until what condition is met?
A. The counter variable is greater than the terminating value.
B. The counter variable is equal to or greater than the terminating
value.
C. The counter variable is less than the terminating value.
D. The counter variable is less than or equal to the terminating
value. Answer: C


◉ What is the value of j after the end of the following code segment?
For j As Integer = 1 to 23
lstBox.Items.Add("The counter value is " & j)
Next
A. 22
B. 23
C. 24
D. j no longer exists. Answer: D

,◉ The following two sets of code produce the same output. (T/F)
Dim num As Integer = 1
Do While num <= 5
lstBox.Items.Add("Hello")
num+= 1
Loop


Dim num As Integer = 1
Do
lstBox.Items.Add("Hello")
num += 1
Loop Until (num > 5)


A. True
B. False. Answer: A


◉ A variable declared inside a Do loop can be used or referred to
outside of the loop. (T/F)
A. True
B. False. Answer: B

◉ In analyzing the solution to a program, you conclude that you
want to construct a loop so that the loop terminates either when (a =
20) or when (b > 15). Using a Do loop, the test condition should be
A. Do While (a <> 20) Or (b < 15)
B. Do While (a <> 20) Or (b <= 15)
C. Do While (a <> 20) And (b < 15)
D. Do While (a <> 20) And (b <= 15)
E. Do While (a = 20) And (b > 16). Answer: D

lstBox.Items.Add(num)
Loop
End Sub
A. 6,7
B. 6,7,8
