VB求数组中最大值和它的位置

随机产生10个不同的两位整数存到一维数组，求最大值，还有它的位置
我写了个能求最大值，但不知道怎么求它的原来位置
请补充一下。
Private Sub Command1_Click()
Dim a(1 To 10) As Integer, work As Boolean, i As Integer, j As Integer, x As Integer
Randomize
For i = 1 To 10
a(i) = Int((90 * Rnd) + 10)
Print a(i)
Next i
Print
For i = 10 To 2 Step -1
work = True
For j = 1 To i - 1
If a(j) > a(j + 1) Then
x = a(j)
a(j) = a(j + 1)
a(j + 1) = x
work = False
End If
Next j
If work Then Exit For
Next i
Text1.Text = a(10)
End Sub

Answer 1

定义一个q1，初始值为a(0)，每次判断a(j) > a(j + 1) 成立时，q1=j

此时q1就为所求位置，但是初始位置是0，所以要准确时q1=q1+1

如下所示：

Private Sub Command1_Click()

Cls

Dim a(1 To 10) As Integer, b(1 To 10) As Integer, work As Boolean, i As Integer, j As Integer,

x As Integer

Randomize

For i = 1 To 10

a(i) = Int((90 * Rnd) + 10)

Print a(i)

b(i) = a(i)

Next i

Print

For i = 10 To 2 Step -1

work = True

For j = 1 To i - 1

If a(j) > a(j + 1) Then

x = a(j)

a(j) = a(j + 1)

a(j + 1) = x

work = False

End If

Next j

If work Then Exit For

Next i

Text1.Text = a(10)

For k = 1 To UBound(a)

If b(k) = a(10) Then

MsgBox "原来位置：" & k, 64, "提示!"

Exit For

End If

Next k

扩展资料：

有两种方法定义数组： 

1、知道数组的元素个数，那么直接定义。

dim a(9) as integer 

2、暂时不知道元素个数，或者该数组应用在多个地方，那么如下定义。

dim a() as integer

在使用的时候，再重定义一下就可以了。

ReDim a(9)

数组的类型可以和变量的类型一样的。

dim a(0 to 9) as string '表示定义了一个包含10个元素的字符串型的数组，数组名为：a

Answer 2

在你基础上，我加了几句代码就可以了：
Private Sub Command1_Click()
Cls
Dim a(1 To 10) As Integer, b(1 To 10) As Integer, work As Boolean, i As Integer, j As Integer, x As Integer
Randomize
For i = 1 To 10
a(i) = Int((90 * Rnd) + 10)
Print a(i)
b(i) = a(i)
Next i
Print

For i = 10 To 2 Step -1
work = True
For j = 1 To i - 1
If a(j) > a(j + 1) Then
x = a(j)
a(j) = a(j + 1)
a(j + 1) = x
work = False
End If
Next j
If work Then Exit For
Next i
Text1.Text = a(10)

For k = 1 To UBound(a)
If b(k) = a(10) Then
MsgBox "原来位置：" & k, 64, "提示!"
Exit For
End If
Next k

Answer 3

我就简单说了

定义一个q1，初始值为a(0)，每次判断a(j) > a(j + 1) 成立时，q1=j

此时q1就为你的位置，但是初始位置是0，所以要准确时q1=q1+1
