输入任意长度的字符串，要求将字符顺序倒置。如输入“ABCD”，则倒置后为“DCBA”。要求源串和倒置后的目标串都输出。（要求用数组来实现）

估计是老师出的让你熟悉数组使用的题目....

vb里面内置一个 StrReverse 函数,可以直接把字符串顺序倒置....

Private Sub Form_Load()
Dim strYuan As String
Dim arr() As String
Dim strDao As String
Dim i As Long
strYuan = "ABCDE"

ReDim arr(Len(strYuan) - 1)

For i = 1 To Len(strYuan)
arr(i - 1) = Mid$(strYuan, i, 1)
Next

For i = UBound(arr) To 0 Step -1
strDao = strDao & arr(i)
Next

Me.Show

Print "原字符串:" & strYuan
Print "倒置符串:" & strDao

MsgBox StrReverse(strYuan)

End Sub
