1. Determine the output displayed when the button is clicked.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;?Triple a number;Dim num As Double = 5;lstOutput.Items.Add(Triple(num));lstOutput.Items.Add (num);End Sub;Function Triple(ByVal x As Double) As Double;Dim num As Double = 3;Return num * x;End Function;2. Determine the output displayed when the button is clicked.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;Dim states, senators As Double;States = 50;Senators = 2;Senate(states * senators);End Sub;Sub Senate (ByVal num as Double);txtBox.Text = ?the number of U.S. Senators is ? & num;End Sub;3. Find the errors.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;Dim word As String, number As Double;word = ?seven?;number = 7;Display (word, number);End Sub;Sub Display(ByVal num As Double, ByVal term As String);textOutput.Text = num & ? ? & term;End Sub;4. Rewrite the program so input, processing, and output are each performed by calls to Sub procedures.;Private Sub btnCompute_Click(...) Handles btnCompute.Click;?Information about trees;Dim num As Integer = 7;Tree = ?redwood?;ht = 362;lstBox.Items.Add(?The tallest ? & tree & ? tree in the U. S, is ? & ht & & ? feet.?);tree = ?pine?;ht = 223;lstBox.Items.Add(?The tallest ? & tree & ? tree in the U. S. is ? & ht & ? feet.?);End Sub;5. Determine the output displayed when the button is clicked.;Private Sub btnDetermine_Click(...) Handles btnDetermine.Click;Dim word As String = ??;Dim num As Integer;GetFacts(word, num);txtOutput.text = ?The first ? & num & ? letters of ? & word & ? are ? & BegOfWord(word, num) & ?.?;End Sub;Sub GetFacts(ByRef w As String, ByRef num As Integer);w = InputBox(?enter a word: ?);n = CInt(InputBox(?Enter a number less than the length of the word: ?));End Sub;Function BefOfWiord(ByVal word As String, ByVal num As Integer) As String;Return word.Substring(0, num);End Function;(Assume the two responses are Education and 3.);6. Determine the output displayed when the button is clicked.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;Dim price, markdown, salesTax, finalCost as Double;InputData(price, finalCost);finalCost = CostOfItem(price, markdown, salesTax);DisplayOutput(price, finalCost);End Sub;Sub InputData (ByRef price As Double, ByRef markdown As Double, ByRef salesTax As Double);Price = CDbl(InputBox(?Price of item: ?);Markdown = CDbl (InputBox(?Percentage discount: ?));salesTax = CDbl(InputBox(?Percentage state sales tax: ?));End Sub;Function CostOfItem(ByVal pr As Double, ByVal md As Double, ByVal st As Double) As Double;Dim reducedPrice, cost As Double;reducedPrice = pr ? ((md/100) * pr);cost = reducedPrice + ((st / 100) * reducedPrice);Return cost;End Function;(Assume the three responses are 125, 20, and 6);7. Identify the errors.;Private Sub btnDisplay_Click(...) Handles btnDisplay.Click;Dim word As String;word = InputBox("What is your favorite word?");txtOutput.Text = "When the word is written twice,;Twice(word) & " letters are used.;End Sub;Function Twice(ByVal w As String) As Integer;Compute twice the length of a string;Dim len As Integer;Return len = 2 * w.Length;End
