[单项选择题] 有过程如下：Sub fact (m As Integer, total As Long)Dim i As Integertotal = 1for i = 1 To mtot

[单项选择题] 有过程如下：Sub fact (m As Integer, total As Long) Dim i As Integer total = 1 for i = 1 To mtot

[单项选择题] 有过程如下：Sub fact (m As Integer, total As Long) Dim i As Integer total = 1 for i = 1 To mtotal = total*i Next iEnd Sub调用它的事件过程如下：Private Sub Command1_ Click () Dim tot As Long Dim a As Integer a = Val InputBox (“请输入数据”)) Call fact (a, tot) Print totEnd Sub则输入数据5，运行结果为 ______。

A．100

B．120

C．200

D．50

正确答案：

B

参考解析：

本题难点是实、虚参数传递的问题。tot按ByRef参数传递。子过程的功能是计算 n!，“5!=120”。
