定义一个有20个元素的一维数组，使用InputBox函数为数组中的所有元素赋值，并显示其中的最大值与最小值

Question

请标明使用的控件，及控件属性，谢谢

Answer 1

'1、在名称为Form1，标题为“数组为参数”的窗体上有两个命令按钮C1，C2，标题分别为”输入显示”，“退出”；
'2、两个文本框Text1,Text2,初始内容为空，两个标签L1,L2，标题为标题分别为“数组中的最大值”和“数组中的最小值”。
'3、在Text1和Text2中分别显示出最大值和最小值。单击C2退出程序。

Private Sub C1_Click()
Dim array1(0 To 19) As Double
Dim a As Double
Dim b As Double

For i = 0 To 19
array1(i) = Val(InputBox("输入数值"))
Next i
Call max(array1, a, b)
Text1 = a
Text2 = b
End Sub

Private Sub C2_Click()
Unload Me
End Sub

Private Sub Form_Load()
Me.Caption = "数组为参数"
Text1 = ""
Text2 = ""
L1.Caption = "数组中的最大值"
L2.Caption = "数组中的最小值"
C1.Caption = "输入显示"
C2.Caption = "退出"
End Sub

Sub max(array1, a, b)
For i = 0 To UBound(array1) - 1
For j = UBound(array1) - 1 To i Step -1
If array1(j) > array1(j + 1) Then
a = array1(j)
array1(j) = array1(j + 1)
array1(j + 1) = a
End If
Next j
Next i
a = array1(UBound(array1))
b = array1(0)
End Sub

Answer 2

窗体上添加两个command，然后使用以下代码：
Dim a() As Single, i As Integer, j As Integer
Private Sub Command1_Click()
ReDim a(1 To 20) As Single
Cls
For i = 1 To 20
a(i) = Val(InputBox("请输入第" & i & "个元素的值"))
Next i
End Sub

Private Sub Command2_Click()
For i = 1 To 19
For j = i + 1 To 20
If a(i) > a(j) Then
t = a(i): a(i) = a(j): a(j) = t
End If
Next
Next
Print "最小值元素：" & a(1) & vbCrLf & "最大元素：" & a(20)
End Sub

Private Sub Form_Load()
Command1.Caption = "输入数组"
Command2.Caption = "显示"
