某个窗体已编写以下事件过程。打开窗体运行后，单击窗体，消息框的输出结果为
Private Sub Form_Click()
a=1
i=1
Do Until i＞10
a=a+2
i=i+3
Loop
MsgBox a
End Sub

答案

参考答案：I

解析：本题考查VBA中循环的知识。对于这种循环结构，首先看条件判断在循环体的前面还是后面，如果是先判断条件，则有可能一次也不执行循环体；如果是后判断条件，则无论条件如何至少执行一次循环体。在Until循环中条件为False时执行循环体，条件为True时退出循环；在While循环中条件为True时执行循环体；条件为False时退出循环，这一点要注意区分清楚。本题中先判断条件后执行循环体，通过观察看出，i每次自加3，则每次循环中i的值分别为1、4、7、10，当i为13时由于满足Until条件而退出循环，所以循环共执行4次，最后a的值为9。
