编一VB程序，显示出所有的水仙花数。

Question

如153是水仙花数，因为153=1^3+5^3+3^3
利用一个单循环将一个三位数逐位分离后进行判断。
如 do while s>0
s1=s mod 10
s=s \10
loop
Private Sub Form_Click()
Dim i%, j%, m%
s = i * 100 + j * 10 * m
Do While s > 0
s1 = s Mod 10
s = s \ 10
要用单循环，请不要用三重循环
Print s1;
If i ^ 3 + j ^ 3 + m ^ 3 = i * 100 + j * 10 + m Then
Print Str(i * 100 + j * 10 + m)
End If
Loop

End Sub
有什么错误吗？

Answer 1

Dim i%, j%, m%
s = i * 100 + j * 10 * m '一定=0
Do While s > 0 '一定不成立
'"水仙花数"
Private Sub Form_Click()
Dim a, b, c As Integer 'a(个)b(十)c(百)
For a = 0 To 9
For b = 0 To 9
For c = 1 To 9
If a ^ 3 + b ^ 3 + c ^ 3 = a + 10 * b + 100 * c Then
MsgBox 100 * c + 10 * b + a
End If
Next c
Next b
Next a
End Sub

For n = 100 To 999

j = (n Mod 100) \ 10

If i ^ 3 + j ^ 3 + m ^ 3 = n Then
