一个两位数的正整数,如果将其个位数与十位数对调所生成的数称为对调数,如28是82的对调数.现给定一个两
Dim a As Integer,b As Integer,c As Integer
Dim d As Integer,e As String,f As String
Private Sub Command1_Click()
f = InputBox("请输入一个两位数")
a = Val(f)
b = Val(Right(f,1)) * 10 + Val(Left(f,1))
c = 9
Do Until c >= 100
c = c + 1
e = Str(c)
d = Val(Right(e,1)) * 10 + Val(Left(e,1))
If a + b = c + d Then
Print a,b,c,d
End If
Loop
End Sub
为什么这个程序print输出为空?

没有满足你的表达式的数呗
看一下你的表达式错没有?
If a + b = c + d Then
笑年1977答案是错的，结果只是两个数对调位置而已，比如23+32＝32+23，结果这个。
应该这样才可以
Private Sub Form_Click()
Me.Cls
Dim Num As Integer, i As Integer
Do
Num = Int(Val(InputBox("输入2位数")))
Loop While Len(C...

Next i
End Sub
Private Function Chg(N As Integer) As Integer
Chg = Mid(CStr(N), 2, 1) & Mid(CStr(N), 1, 1)
End Function
收起
If （a + b ）== （c + d ）Then
