Choose Two questions to answer. Only first two answers will be graded.
You may cross out the answer to avoid grading. Assume there is no syntax or logic error in the
codes. The ToString method converts a value to string value.
1. Determine the value of intTotal displayed in the message box once the following codes
are executed (10 points). What will be the number of iterations of the loop (the number
of times the loop will execute the codes inside of the loop)? Explain (40 points).
Dim intCounter As Integer = 0
Dim intTotal As Integer = 0
Do While intCounter < 5
intCounter = intCounter + 2
intTotal = intTotal + 10
Loop
MsgBox(intTotal.ToString)
2. Determine the value of intTotal displayed in the message box once the following codes
are executed (10 points). What will be the number of iterations of the loop (the number
of times the loop will execute the codes inside of the loop)? Explain (40 points).
Dim intCounter As Integer
Dim intTotal As Integer = 0
For intCounter = 1 To 5 Step 2
intTotal = intTotal + 10
Next intCounter
MsgBox(intTotal.ToString)

3. Based the GUI with the input value and the codes below, determine the output of the
program when it is executed (10 point). Explain how (40 points).
Private Sub btnFindOut_Click(……..) Handles btnFindOut.Click
Dim intCentimeter As Integer
Dim blnGoodToGo As Boolean = True
'Read Input Value
intCentimeter = Val(txtCentimeter.Text)
'Process and Output
Select Case intCentimeter
Case Is < 10
If Not ( blnGoodToGo = True ) Then
MsgBox("It is shorter than 10 centimeters and good to go.")
Else
MsgBox("It is shorter than 10 centimeters and not good to go.")
End If
Case 1
If blnGoodToGo = True Then
MsgBox("It is 1 centimeter and good to go.")
Else
MsgBox("It is 1 centimeter and no good to go.")
End If
End Select
End Sub
