Private Sub Command1_Click()
a = Val(Text1.Text)
b = Val(Text2.Text)
c = Val(Text3.Text)
If a < b Then
t = a: a = b: b = t
End If
If a < c Then
t = a: a = c: c = t
End If
If b < c Then
t = b: b = c: c = t
End If
Text4.Text = a & "," & b & "," & c
End Sub
本程序中If a < b Then
t = a: a = b: b = t实现了什么
怎么解释,请指教一下 谢谢
