B类似main函数，貌似也没有问题

I think the answer might be D. The reason is that B is used to accept inputs
from the command line. But to provide a variable length of parameters
inside a function, the choice might be D.

来表示变长参数

but I don't know why it ask "use all of them" |

发帖数: 6098 | 8 如果不是类型的问题，B正确吗？
还是这种形式是专门给main用的？
