S=0

For i=20 To 1 Step -5

   S=S+1

Next i

Text1.text=str(s)

文本框中显示的值是（ ）

Dim a(l To 100) As String

Private Sub Commandl_Click()

  Dim c As Integer, t As String, ans As String

  s = Textl. Text

  k = Val(Text2. Text)

  ans =“”

  For i = 1 To Len(s) - k - 1

    c = c + 1

    a(c) = Mid(s, i, 1) + Mid(s, i + k + 1, 1)

    If check(c) Then

      ans = ans + a(c) + "，"

    Else

      c = c - 1

    End If

  Next i

  Text3. Text = ans

End Sub

Function check(k As Integer) As Boolean

  Dim i As Integer

  check = True

  For i = 1 To k - 1

    If a(i) = a(k) Then check = False: Exit For

  Next i

End Function

若该程序段执行后，在文本框Text1中输入的字符串长度不超过10，文本框Text2中输入的值在0到8范围内（输入输出都不包括双引号本身），下列说法不正确的是（  ）

n = 6

d(1) = 23: d(2) = 31: d(3) = 19: d(4) = 33: d(5) =58: d(6) = 28

k = Abs(d(2) - d(1))

For i = 3 To n

 If Abs(d(i) - d(i - 1)) > k Then k = Abs(d(i) - d(i - 1))

Next i

Text1.Text = Str(k)

上述程序段执行后，文本框Text1显示的内容是（  ）

代码如下：

Private Sub Command1_Click()

Dim a(1 To 13) As Integer, i As Integer, j As Integer, n As Integer

For i=1 To 13

  a(i)=0

Next i

i=1:n=0:j=1

Do While i<=13

Do While True

If j>13 Then {#blank#}1{#/blank#}

If a(j)=0 Then n=n+1

If n=i Then

{#blank#}2{#/blank#}

n=0

Exit Do

End If

j=j+1

Loop

{#blank#}3{#/blank#}

Loop

Label1.Caption="原来牌的顺序是："

For k=1 To 13

   Label2.Caption ={#blank#}4{#/blank#}

End Sub

Dima( 1 To 5) As Integer

Dimi As Integer, j As Integer, s As String

s=“”

    For i= 2 To 5

        For j=i To 5

            If j Mod i=0 Then a(j) =a(j)+1

        Next j

    Next i

    For i= 1 To 5

        If a(i) <>1Then s=Str(i) +s

    Next i

    Text 1．Text=S

若数组a的初始值都为0，则运行该程序段后，Text 1中显示的内容为（  ）
