实现上述功能的VB程序如下，但加框处代码有错，请改正。

Const  n = 50

Dim d(0 To n) As single , name(1 to n) as string

'读入50个学生的身高，依次存入d(1)…d(50),姓名存入name(1)…name(50) '代码略

Private Sub Command1_Click()

Dim i As Integer, j As Integer, temp As single, k As Integer,r as string

d(0) = 2

For i = 1 To 10

    ①

    For j = i To n

     If d(j) < d(i - 1) Then

         If     ②  Then

           k = j

        End If

     End If

  Next j

  If k <> i Then

     temp = d(k):  d(k) = d(i):  d(i) = temp

     r=name(k) : name(k)=name(i) : name(i)=r

  End If

Next i

For i = 1 To 10   ‘输出被选的10个人的名字和身高。

  List2．AddItem  name(i) & d(i)

执行该程序段后，在文本框Text1中显示的是（  ）
