vb中怎样在一组有序一维数组中插入指定数字并使其新数组按照从小到大的顺序排列 下面是我的代码

VB 在一个有序数组中插入指定数字并使其仍然有序,下面是我的代码。。12

Option Base 1
Dim a() As Integer, n As Integer, i As Integer
Private Sub Command1_Click()

n = Val(InputBox("输入数组个数"))
ReDim a(n)
Randomize
For i = 1 To n
a(i) = Int(90 * Rnd) + 10
List1.AddItem a(i)
Next i
End Sub
Private Sub Command2_Click()
Dim t As Integer
For i = 1 To n
For j = 1 To n - i
If a(j) > a(j + 1) Then
t = a(j)
a(j) = a(j + 1)
a(j + 1) = t
End If
Next
Next
For i = 1 To n
List2.AddItem a(i)
Next i
End Sub
Private Sub Command3_Click()

首先click要清除list窗口，不然会累加，问了两次，分不要浪费了！！
Option Base 1
Dim a() As Integer, n As Integer, i As Integer
Private Sub Command1_Click()
List1.Clear
List2.Clear
n = Val(InputBox("输入数组个数"))
ReDim a(1 To n)
Randomize
For i = 1 To n
a(i) = Int(90 * Rnd) + 10
List1.AddItem a(i)
Next i
End Sub
Private Sub Command2_Click()
List2.Clear
Dim t As Integer
For i = 1 To n
For j = i To n
If a(i) > a(j) Then
t = a(j)
a(j) = a(i)
a(i) = t
End If
Next j
Next i
For i = 1 To n
List2.AddItem a(i)
Next i
End Sub
Private Sub Command3_Click()
Dim i%, j%, x%
x = Val(InputBox("插入的数"))
For i = n To 1 Step -1
If x > a(i) Then Exit For
Next i
ReDim Preserve a(UBound(a) + 1)
For j = UBound(a) To i + 1 Step -1
a(j) = a(j - 1)
Next j
a(i + 1) = x
List2.Clear
For i = 1 To UBound(a)
List2.AddItem a(i)
Next i
End Sub
这样可以了吧？
