小李基于冒泡排序算法编写了一个VB程序,功能如下:在文本框Text1中显示排序前的数据,单击“排序”按钮Command1,在文本框Text2中显示剔除重复数据后的升序排序结果。程序运行界面如图所示。
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 = 10
Dim a(1 To n)As Integer
Private Sub Commandl_Click()
Dim i As Integer,j As Integer,t As Integer
Dim bottom As Integer
'获取排序前数据依次存储在数组a中,并在文本框Text 1中显示。代码略
bottom = n
i = 1
Do While i<= bottom-1
For j = bottom To i + 1 Step -1
If Then ‘⑴
t = a(j): a(j)= a(j - 1):a(j - 1)= t
Elself a(j)= a(j - 1)Then '相邻两个数据相等,进行剔除处理
‘⑵
bottom = bottom -1
End If
Next j
i = i+1
Loop
Text2.Text=""
For i = 1 To bottom
Text2.Text = Text2.Text+Str(a(i))
Next i
End Sub
