数据插入。用VB设计程序，主要功能如下：随机产生15个200以内的正整数数列，按升序排序后显示在List1列表框中，在文本框Text1中输入1个200以内的正整数，单击“插入”按钮Command1后将其插入到数列中，并保持数列仍然有序，显示在列表List2中，同时在标签Label4中显示插入的位置，程序界面如图所示。

实现上述功能的VB程序代码如下，请在划线处填上合适的代码。

Dim a( 1 To 20) As Integer

Private Sub Command1_Click ( )

Dim key As Integer

key = ①

i = 1

Do While key > a ( i ) And ( i <= 1 5 )

i = i + 1

Loop

Label4.Caption = “该数插入的位置是：” + Str ( i )

If i = 16 Then

a ( i ) = key

Else

For j = 16 To i + 1 Step -1

②

Next j

a ( i ) = key

End If

List2. Clear

For i = 1 To 16

List2.AddItem a( i)

Next i

End Sub

Private Sub Form_Load( )

'随机生成15个200以内的正整数

Randomize

For i = 1 To 15

a ( i ) = Int(Rnd * 200) + 1

Next i

'将15个数从小到大排序

For i = 1 To 14

k = i

For j = i + 1 To 15

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

Next j

If i <>k Then

t = a(i)； a( i) = a ( k )：a ( k )

End If

Next i

'将排好序的数输出在列表框Listl中

Listl.Clear

For i = 1 To 15

Listl.AddItem str ( a ( i ) )

Next i

End Sub
