vb编程：定义一个数组A（10），对数组中的元素排降序。要求排序算法用子程序过程实现。

Private Sub Command1_Click()
Dim a(10) As Integer, i As Integer
Print "随机生成数组："
For i = 1 To 10
a(i) = Int(Rnd * 100) + 1
Print a(i);
Next i
Print
Print "降序排序后为："
Call px(a)
End Sub

Sub px(a() As Integer)
For j = 1 To 9
For i = 1 To 9
If a(i) < a(i + 1) Then temp = a(i + 1): a(i + 1) = a(i): a(i) = temp
Next i
Next j
For i = 1 To 10
Print a(i);
Next i
End Sub
