Question

1. Determine the output displayed when the button is clicked.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;Dim num As Double = 0;Dim max As Double = -1;Dim prompt As String = ? Enter a nonnegative number. ? & Enter -1 to terminate entering numbers.?;Num = CDbl(Input Box(prompt));Do While num >= 0;If num > max Then;Max = num;End If;Num = CDbl(InputBox(prompt));Loop;If max <> -1 Then;MessageBox.Show(?Maximum number: ? & max);Else;MessageBox.Show(?No numbers were entered.?);End If;Assu,me that the responses are 4, 7, 3, and -1);2. Replace each phrase containing "Until" with an equivalent phrase containing "While", and vice versa. For instance, the phrase (Until sum = 100) would be replaced by (While sum <> 100).;While (ans = "Y") And (n < 7);3. Determine the output displayed when the button is clicked.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;Dim word As String = ?courage?;Dim letter As String = ??;Dim numVowels As Integer = 0;For i As Integer = 0 To word.length ? 1;Letter = word.Substring(I, 1);If IsVowel (letter) Then;numVowels += 1;End If;Next;txtBox.Text = CStr(numVowels);End Sub;Function IsVowel(ByVal letter As String) As Boolean;Letter = letter.ToUpper;If (letter = ?A? Or (letter = ?E?) Or (letter = ?I?) Or (letter = ?O?) Or (letter = ?U?) Then;Return True;Else;Return False;End If;End Function;4. Rewrite the program using a For?Next loop.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;Dim num as Integer = 1;Do While num <= 9;lstBox.Items.Add(num);num += 2;Loop;End Sub;5. Identify the errors.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;?Display all numbers from 0 through 20 except for 13;For i As Integer = 20 to 0;If i = 13 Then;i = 12;End If;Next;End Sub;(Assume that the five lines of the file DATA.TXT contain the following entries: 3, 2, 4, 7, 2.);6. Determine the contents of the text box after the code is executed.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;Dim total As Integer = 0;For n As Integer = 0 To lstBox.Items.Count ? 1;If CStr(lstBox.Items(n)).Length = 6 Then;Total += 1;End If;Next;txtOutput.Text = CStr(total);End Sub;7.
