你是否相同Nehil谁正在为C（*）写一个垃圾收集器？
？如果是这样，你有没有听过

的建议走路之前走路？

Are you the same "Nehil" who is undertaking to write
a garbage collector for C (*)? If so, have you ever heard the
advice "Walk before you run?"

(*) And, no doubt, next week, the Mars lander program.

你改变了自己的名字或者和Eric Sosman一样吗？

好​​了，如果我想学习很多辩论的新概念怎么办？ 。现在垃圾收集器几乎完成了一个低级别的项目。

并且

我所询问的所有事情都只是以某种方式与这个项目有关。

Nehil说：

Nehil said:

C是一种100％的按值调用语言。函数参数是表达式，

不是对象。评估这些表达式，并将这些值传递给函数。

C is a 100% call-by-value language. Function arguments are expressions,
not objects. These expressions are evaluated, and those values are
passed to the function.
