举一反三
- 在窗体上添加一个命令按钮Command1和3个标签Label1、Label2、Label3，然后编写如下代码。 Private x As Integer Private Sub Command1_Click() Static y As Integer Dim z As Integer n = 10 z = n + z y = y + z x = x + z Label1.Caption = x Label2.Caption = y Label3.Caption = z End Sub 运行程序，连续 3 次单击命令按钮后，则 3 个标签中显示的内容分别是（ ）。
- 设窗体上有一个Command1命令按钮，还有以下程序代码： Private Sub Command1_Click() Static x As Integer x=x+1 Call proc(x) Print x, End Sub Private Sub proc(a As Integer) Static x As Integer x=x+a：a=x End Sub 程序运行后，3次单击命令按钮，则产生的输出是 A: 1 2 3 B: 1 3 5 C: 1 3 7 D: 2 4 6
- 运行下面的程序，第二行显示结果是___________。 Private Sub Form_Click() Dim A As Integer Dim i As Integer A = 5 For i = 1 To 9 Call sub1(i, A) Print i, A Next i End Sub Private Sub sub1(x As Integer, y As Integer) Static N As Integer Dim I As Integer For I = 3 To 1 Step -1 N = N + x x = x + 2 Next I y = y + N End Sub
- 设有如下通用过程，在窗体上画一个名称为command1的命令按钮，然后编写如下事件过程： private sub command1_click() dim x as integer x=10 y=5 y=f(x) print x;y end sub public function f (x as integer) dim y as integer x=20 y=2 f=x*y end function 程序运行后，如果单击命令按钮，则在窗体上显示的内容是（）
- 编写如下程序： Private Sub Command1_Click() Dim x As Integer, y As Integer x = 1: y = 1 Do y = x * y If y > 10 Then Print x, y Exit Do Else x = x + 3 End If Loop While x <= 10 End Sub 运行程序，输出结果为______

在窗体上画一个命令按钮Command1，编写事件代码如下： Public x As Integer Private Sub Command1_Click() x=3 Call f1 Call f2 MsgBox x End Sub Private Sub f1() x=x*x End Sub Private Sub f2() Dim x As Integer x=x+4 End Sub 运行窗体后，单击命令按钮，则消息框的输出结果为______。

有如下事件程序,运行该程序后输出结果是。 Private Sub Command33_Click() Dim x As Integer, y As Integer x = 1: y = 0 Do Until y <= 25 y = y + x * x x = x + 1 Loop MsgBox "x=" & x & ", y=" & y End Sub

在窗体中添加一个命令按钮(名为Command1)，然后编写如下代码： Public x as integer Private Sub Command1_Click( ) x=5 Call s1 Call s2 MsgBox x End Sub Private Sub s1( ) x=x+10 End Sub Private Sub s2( ) Dim x as integer x=x+10 End Sub 窗体打开运行后，单击命令按钮，则消息框的输出结果是______
- 3
有如下函数过程： Function secproc(x As Integer, y As Integer, z As Integer) secproc = 3 * y + z + 2 * x End Function Private Sub Command1_Click() Dim a As Integer, b As Integer, c As Integer a = 2: b = 3: c = 4 Print secproc(c, b, a) End Sub 该程序的运行结果是（ ）。

Sub s1(ByVal x As Integer, ByVal y As Integer) Dim t As Integer t = x: x = y: y = t End Sub Sub s2(x As Integer, y As Integer) Dim t As Integer t = x: x = y: y = t End Sub 则以下说法中正确的是( )。
