窗体上有3个文本框Text1、Text2、Text3和一个命令按钮Command1。如果在Text1中输入200,在Text2中输入150,则执行下列程序后,Text3的值为( )。 Private Sub Command1_Click() Dim m, n, t As Integer m = Val(Text1.Text) n = Val(Text2.Text) If n * m = 0 Then Exit Sub End If If m < n Then t = m: m = n: n = t End If Do r = m Mod n m = n n = r Loop While r <> 0 Text3.Text = m End Sub
