1. Determine the first two lines of the new file created by the code below. This exercise refers to the file Justices.txt that contains data about the Supreme Court justices, past and present. Each record contains six fields – first name, last name, appointing president, home state, year appointed, and year they left the court. If they are still on the court, the last field is set to 0. The first two lines of the file are as follows:




 Samuel, Alito, George W. Bush, NJ, 2006, 0




 Henry, Baldwin, Andrew Jackson, PA, 1844




 Dim query = From line Int IO.File.ReadAllLines(“Justices.txt”)




             Let data = line.Split(“,”C)




             Let firstName = data(0)




             Let lastName = data(1)




             Let fullName = firstName & “ “ & lastName




             Let state = data(3)




             Select fullName & “’” & state




 IO.File.WriteAllLines(“NewFile.txt”, query)








2. Describe the new file created by the code.




 Dim query = From line In IO.File.ReadAllLines(“Justices.txt”)




             Let data = line.Split(“,”c)




             Let firstName = data(0)




             Let lastName = data(1)




               Let state = data(3)




             Let yrAppointed = CInt(data(4))




             Let fullName = firstName & “ “ & lastName




             Let newLine = state & “, “ & fullName




             Where (yrAppointed >= 1990) And (yrAppointed < 2000)




             Order By yrAppointed




             Select newline




 IO.File.WriteAllLines(“NewFile.txt”, query)








3. Determine the output displayed in the text box when the button is clicked.




  Private Sub btnDisplay_Click(…) Handles btnDisplay.Click




    Dim salutation, welcome As String




    Dim sw As IO.StreamWriter = IO.File.CreateText(“Greetings.txt”)
















    Dim sr As IO.StreamReader = IO.File.OpenText(“Greetings.txt”)




    salutation = sr.Readline




    welcome = sr.Readline








    txtOutput.Text = welcome




 End Sub








4. Identify any errors. Assume that the contents of the Greetings.txt file are:












 Bon Jour




 Private Sub btnDisplay_Click(…) Handles btnDisplay.Click




    Dim name, greeting As String




    Dim sr As IO.StreamReader = IO.File.OpentText(“Greetings.txt”)




    name = “NewGreet.txt”




   Dim sw As IO.StreamWriter = IO.CreateText(“name”)




    Do Until sr.EndOfStream




       greeting = sr.Readline




















 End Sub








5. The first two lines of the file AgetAtInaug.txt are




 George Washington, 57

             John McCain, Arizona, R




                 Joseph Lieberman, Connecticut, I
