If x>100 then

      Y=12

        ①       x>60 then

      Y=8

     Else 

y=5

        ②   

该程序段中，①处填写的内容为{#blank#}1{#/blank#}；②处填写的内容为{#blank#}2{#/blank#}。

实现上述功能的VB程序如下,请回答下列问题:

k = 1

For j = 2 To 100

If a(j) > a(k) Then k = j

Next j

x = a(k)
该程序段执行后，变量x中存储的是（  ）

Private Sub Command 1_Click()

Dim i As Integer

Dim t As Integer

Dim s As String

i = 1:t = 1:n = Text1.Text

List1.Clear

Do While t< = n

  s = s + “*”

  If i = t Then

  List1.AddItem s

  t = t + 1

  i=0

 End If

i = i + 1

Loop

End Sub
