举一反三
- 下列程序: Option Base 1 Private Sub Form_Click() Dim a(5，5) For i ＝ 1 To 5 For j ＝ 1 To 5 k ＝ k ＋ 1 a (i，j)＝ k Next j Next i For i ＝ 1 To 5 s ＝ s ＋ a (i，i) Next i Print s End Sub 运行时的输出结果是( )。
- 窗体的单击事件过程如下：Private Sub Form_Click() K = 1 For i = 5 To 1 Step -1 T = T * 10 + K S = S + T Next i Print SEnd Sub运行程序时，单击窗体后，显示的是 A: 12345 B: 54321 C: 0 D: 11111
- 运行下列程序，单击窗体显示的结果为（ ）。 Private Sub Form_Click() Dim a Dim s As Integer, i As Integer a = Array(1, 2, 3) For i = 2 To 0 Step -1 s = s + a(i) * a(i) Next i Print s End Sub
- 求 1!+2!+......+20!的值。 Private Sub Form_Click() Dim i%, t!, s! s = 1 t = 1 '**********SPACE********** For i = 【1】 To 20 t = t * i '**********SPACE********** s = 【2】 '**********SPACE********** 【3】 Print s End Su
- 下面程序的输出结果是 Private Sub Command1_Click() ch$="ABCDEF" proc ch Print ch End Sub Private Sub proc(ch As String) S="" For k=Len(ch) To 1 Step-1 s=s & Mid(ch,k,1) Next k ch=s End Sub
