Dim a(1 To 5) As Integer

Dim f As Boolean

a(1) = 23: a(2) = 12: a(3) = 56: a(4) = 34: a(5) = 10

i = 1: f = True

Do While i <= 5 And f = True

  If a(i) = 56 Then f = False

该程序运行后，在列表框List1中显示的是（  ）

Private Sub Command1_Click()

  Dim s As String, a As String, t As String

  s = Text1.Text: t = ""

  For i = 1 To Len(s)

    a = Mid(s, i, 1)

    If a >= "0" And a <= "9" Then

      t = t + a

    ElseIf a = "!" Then

      t = ""

    ElseIf t <> "" Then

      List1.AddItem t

    End If

  Next i

End Sub

在文本框Text1中输入“12+23=35!456Ye”，单击按钮“Command1”后，在列表框List1中显示的结果是（  ）

For i= 1 To 2

    For j=5 To i+1 Step-1

      If a(j) >a(i) Then

        t=a(j)：a(j)=a(i)：a(i)=t

      End If

    Next j

Next i

数组元素a(1)到a(5)的值依次为“33，24，45，16，77”，经过该程序段“加工”后，数组元素a(1)到a(5)的值依次为（  ）

i=0

while i<6:

   print

   i=i+1
