编程找出10000以内所有的回文数的平方仍是回文数的数

Private Sub Command1_Click()
Dim i As Long, s As String, t As String
For i = 1 To 10000
For j = 1 To Len(CStr(i))
s = Mid(CStr(i), j, 1) & s
Next j
If i = CStr(i) Then
a = i * i
For k = 1 To Len(CStr(a))
t = Mid(CStr(a), k, 1) & t
Next k
End If
Next i
If t = CStr(a) Then b = i & "^" & "2" & "=" & a
List1.AddItem b
End Sub
哪里错了啊啊 啊？？
累觉不爱00

错得很多，一是s和t需要初始化为空，二是IF判断应该在循环里面，还有细节错误，而且判断回文应该定义为函数，我下面的程序调试通过的，你可以参考：

Private Sub Command1_Click()
Dim i As Long
For i = 1 To 10000
If chk_hui(i) Then
If chk_hui(i * i) Then MsgBox i
End If
Next i
End Sub

Private Function chk_hui(x) As Boolean
Dim i, s1, s2
s1 = x & ""
s2 = ""
For i = 1 To Len(s1)
s2 = Mid(s1, i, 1) & s2
Next i
chk_hui = s1 = s2
End Function

由于我没有List1，所以我只是把结果msgbox，你自行修改为你要的形式。

我知道你也懂一点的,我列个思路: for i=1 to 10000 { a=i*i j=0 while(a/10) {b[j]=a/10; a=a/10; j++; } a[j]=a; //接收最后一个数 //判断是否回文数 for k=0 to j/2 if(b[k] <> b[j-k]) break; if(k==j/2) 输出b数组; }
