Visual Basic 6.0 快速排序算法实现 - 示例代码及教程

以下是一个使用Visual Basic 6.0编写的快速排序算法的示例代码：

Option Explicit

Sub QuickSort(arr() As Integer, low As Integer, high As Integer)
    Dim pivot As Integer
    Dim i As Integer, j As Integer
    Dim temp As Integer
    
    If low < high Then
        pivot = arr(high)
        i = low - 1
        
        For j = low To high - 1
            If arr(j) <= pivot Then
                i = i + 1
                temp = arr(i)
                arr(i) = arr(j)
                arr(j) = temp
            End If
        Next j
        
        temp = arr(i + 1)
        arr(i + 1) = arr(high)
        arr(high) = temp
        
        QuickSort arr, low, i
        QuickSort arr, i + 2, high
    End If
End Sub

Sub Main()
    Dim arr() As Integer
    Dim size As Integer
    Dim i As Integer
    
    ' 输入数组大小
    size = InputBox("输入数组大小：")
    
    ' 输入数组元素
    ReDim arr(1 To size)
    For i = 1 To size
        arr(i) = InputBox("输入第 " & i & " 个元素：")
    Next i
    
    ' 调用快速排序算法
    QuickSort arr, 1, size
    
    ' 输出排序后的数组
    MsgBox "排序后的数组为：" & Join(arr, ", ")
End Sub

你可以在VB6.0中创建一个新的标准.EXE工程，将以上代码复制到Form1.frm文件中。然后运行程序，按照提示输入数组大小和元素，最后会显示排序后的数组。
