我理解声明函数定义背后的基本原理，例如
int main（）{return 0; } / *空括号* /
已过时，但我无法找出为什么Dennis Ritchie鄙视他们
足以称他们为"。憎恶"评论和/或链接赞赏。

I understand the rationale behind declaring function definitions such as
int main() { return 0; } /* empty parentheses */
obsolete, but I haven''t been able to find out why Dennis Ritchie despised them
enough to call them an "abomination." Comments and/or links appreciated.

IIRC，空的parens与以下相同：
int main（.. 。）;
表示可变数量的参数。 VARARGS
是皮塔饼，并且有依赖于实现的问题。
如果你真的想要一个空的参数列表，
那么适当的声明是：
int main（无效）;
我的大脑对此很模糊，所以如果我做了一个boo-boo
在这里，请更正我。
IIRC, the empty parens is the same as:
int main(...);
which means variable number of arguments. VARARGS
are pita, and have implementation-dependent issues.
If you really want an empty parameter list,
then the proper declaration is:
int main(void);
My brain is fuzzy on this, so if I made a boo-boo
here, please correct me.

不，它不是。这意味着使用第一次遇到的用法来完成原型的
。

No, it doesn''t. It means use the first-encountered usage to complete
the prototype.
