下列程序的输出结果是 。
Private Sub exam1()
a = 1
For i = 1 To 3
Select Case i
Case 1, 3
a = a + 1
Case 2, 4
a = a + 2
End Select
Next i
MsgBox a End Sub
Private Sub exam1()
a = 1
For i = 1 To 3
Select Case i
Case 1, 3
a = a + 1
Case 2, 4
a = a + 2
End Select
Next i
MsgBox a End Sub
举一反三
- 设有如下窗体单击事件过程,则窗体运行后,单击窗体,消息框输出的结果是______。 Private Sub Form_Click() a=1 For i=1 To 3 Select Case i Case 1,3 a=a+1 Case 2,4 a=a+2 End Select Next i MsgBox End Sub
- 设有以下窗体单击事件过程: Private Sub Form_Click() a=1 For i=1 To 3 Select Case i Case 1,3 a=a+1 Case 2,4 a=a+2 End Select Next i MsgBox a End Sub 打开窗体运行后,单击窗体,则消息框的输出内容是
- 编写如下程序: Private Sub Command1_Click； Dim m As Integer, n As Integer m = 2 : n = 1 Select Case m Case 1 Select Case n Case 1 Print "AAA" Case 2 Print "BBB" End Select Case 2 Print "CCC" End Select End Sub 程序运行后,单击命令按钮Command1,输出结果为 A: BBB B: CCC C: AAA D: 1
- 以下程序的运行结果是 Sub s1(b() As Integer) For i = 1 To 4 b(i) = 2 * i Next i End Sub Private Sub Command1_Click() Dim a(1 To 4) As Integer For i = 1 To 4 a(i) = i + 5 Next i s1 a() For i = 1 To 4 Print a(i) Next i End Sub
- 有程序段For i=1 To 3 : Select Case i : Case 1,3 : a=a+1 : Case 2,4 : a=a+2 : End Select : Next i”,如果程序运行后,a的结果为5,则可判断出a的初始值为
