[单项选择题] 某人为计算n! (0<n<=12)编写了下面的函数过程： Private Function fun(n As Integer) As LongDim P As LongP

[单项选择题] 某人为计算n! (0

A．把P=1改为P=n

B．把For k=n-1 To 2 Step-1改为For k=1 To n-1

C．把For k=n-1 To 2 Step-1改为For k=1 To n

D．把For k=n-1 To 2 Step-1改为For k=2 To n

正确答案：

B

参考解析：

题干中的错误在于求n!，却少乘了n，选项B也犯了同样的错误，所以答案选B。
