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（ ）。
已知程序如下：Private Sub p() Static s As Integer Dim i As Integer For i = 1 To 10 Step 2 s = s + i Next i Print s;End SubPrivate Sub Command1_Click() Call pEnd Sub试问：当三次单击命令按钮后，输出为[______]。
一个窗体单击事件过程如下： Private Sub Form_Click() Dim a As Integer, b As Integer, c As Integer a = 6 : b = 15 c = a * b If a > b Then a = a - b Else b = b - a End If Print a, b, c / bEnd Sub试问：当单击窗体后，输出为___________。
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
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
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
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（ ）。
