Loops:
Be careful about infinite loops

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim answer As String

        Do
            answer = InputBox("Pete and Repeat were on a boat. Pete fell off. Who was left?", "Important question", "Repeat")
        Loop While answer = "Repeat"
    End Sub
End Class

Assignment 4:
HW: Modify the above to count how many times the person chose "Repeat". Output this somewhere at the end.
