Because even though it's a little confusing or a little sort of contradictory, the argument count includes the name of the program itself, -- which can actually be int useful because if someone -- if a producer changes the name of a program by renaming a file, you, the program still have access to your own name by this mechanism.
因为即使它有点迷惑的,或有点冲突的,参数计数包括程序的名字,那个可以是int型的,因为如果有谁-,如果程序员通过重命名改变了一个程序的名字,你仍然可以用这个机制,使用你自己的名字。
