在VB中,通过编写程序代码,找出最大的数和最小的数很简单,三个数比较大小也很简单,前今天碰到了一个问题,就是,用VB制作一个小程序,实现十个随机数的排列。
我查了一些资料,在网上找到了有几个很有趣的排列视频。叫做《舞动的排序算法》。看起来很有趣,也很形象,对这个问题很有帮助。地址如下:http://v.youku.com/v_show/id_XMzMyODk4NTQ4.html

具体的方法如下:
打开VB6.0,在Form1中添加两个按钮Command1和Command2,将其Caption属性分别改为“产生十个随机数”和“排序”,添加一个Label控件在代码窗口中输入如下代码:
Option Explicit
Dim c As Integer
Dim t As Integer
Dim flag As Integer
Dim a(9)
Dim p As String
Private Sub Command1_Click()
Dim i As Integer
p = ""
Label1.Caption = ""
a(0) = Int(100 * Rnd + 1)
For i = 1 To 9
c = Int(100 * Rnd + 1)
flag = 1
For t = 0 To i - 1
If c = a(t) Then
i = i - 1
flag = 0
Exit For
End If
Next t
If flag = 1 Then
a(i) = c
End If
Next i
For i = 0 To 9
p = p & " " & a(i)
Next i
Label1.Caption = p
End Sub
Private Sub Command2_Click()
p = ""
Dim j As Integer
Dim i As Integer
Dim temp As Integer
For i = 0 To 9
p = p & " " & a(i)
Next i
Label1.Caption = p
End Sub
第二种代码:
Option Explicit
Dim c As Integer
Dim t As Integer
Dim flag As Integer
Dim a(9)
Dim p As String
Private Sub Command1_Click()
Dim i As Integer
p = ""
Label1.Caption = ""
a(0) = Int(100 * Rnd + 1)
For i = 1 To 9
c = Int(100 * Rnd + 1)
flag = 1
For t = 0 To i - 1
If c = a(t) Then
i = i - 1
flag = 0
Exit For
End If
Next t
If flag = 1 Then
a(i) = c
End If
Next i
For i = 0 To 9
p = p & " " & a(i)
Next i
Label1.Caption = p
End Sub
Private Sub Command2_Click()
p = ""
Dim j As Integer
Dim i As Integer
Dim temp As Integer
'----------每次选最大-------
For j = 0 To 9 - i
If a(j) > a(j + 1) Then
temp = a(j)
a(j) = a(j + 1)
a(j + 1) = temp
End If
Next j
Next i
For i = 0 To 9
p = p & " " & a(i)
Next i
Label1.Caption = p
End Sub
代码有很多种,这只是其中的一小部分,希望对您有用所帮助。
