设有如下程序a =( ):For i = 1 To 3:Select Case i:Case 1,3:a = a + 1:Case 2,4:a = a + 2:End Select:Next i程序运行后,a的值为6,则a的初始值为( )。
Private Sub Form_Click() 单击窗体,窗体上将会打印出:For i = 1 To 5 Print Tab(8 - i); String(i, Format(i));Next i End Sub
Private Sub Form_Click() 窗体上单击后,显示结果为:a=85Select case aCase Is> =60 I=“及格”Case Is> =70 I=“中“Case Is> =80 I=“良”Case else I=“优”End SelectPrint IEnd Sub
一个窗体单击事件过程如下: Private Sub Form_Click() X = Val(Text1.Text):Y = Val(Text2.Text) If X = 0 Or Y = 0 Then Print "不在任何象限内": Exit Sub If X > 0 And Y > 0 Then Print "IN A" If X > 0 And Y < 0 Then Print "IN D" If X < 0 And Y > 0 Then Print "IN B" If X < 0 And Y < 0 Then Print "IN C"End Sub
