Pay very close attention to the parameter types (ByVal vs ByRef)

Spaces count towards the length of a string

Private Sub btnBedrock_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBedrock.Click

 Dim strFullName As String = "Fred Flintstone"

 Dim strSecondName As String = "Barney Rubble" 

 CountLength(strFullName, strSecondName)

 lblEnd.Text = "My favorite was " & strSecondName

End Sub 

Private Sub CountLength(ByVal strFullName As String, ByRef strSecondName As String)

 lblFirst.Text = "The first name has " & strFullName.Length & " letters."

 lblSecond.Text = "The second name has " & strSecondName.Length & " letters."

 strSecondName = "Dino"

End Sub

What value will the lblFirst Label display after the user clicks on the btnBedrock Button?

What value will the lblSecond Label display after the user clicks on the btnBedrock Button?

What value will the lblEnd Label display after the user clicks on the btnBedrock Button?
