vb编程产生20个200以内的随机数并从大到小排序输出

Private Sub Command1_Click()

  Dim a(20) As Integer

  Print "产生的数："

  For i = 1 To 20

    a(i) = Int(Rnd * 201)

    Print a(i);

  Next i

  Print

  For i = 1 To 19

    For j = 1 To 20 - i

      If a(j) < a(j + 1) Then

        t = a(j): a(j) = a(j + 1): a(j + 1) = t

      End If

    Next j

  Next i

  Print "排序以后："

  For i = 1 To 20

    Print a(i);

  Next i

  Print

End Sub
