参数评估顺序 [英] Order of parameter evaulation
问题描述
男孩，我敢肯定这是一个FAQ。
很多年前，我的编程语言的运行时行为教授
绝对保证C参数从左到右进行评估。
他是来自CMU的聪明人，他的研究重点是编程
语言，我相信他，但现在我不太确定。
一点帮助？

布什正吹着它。
Boy, I''ll sure bet this is a FAQ.
Many years ago, my "runtime behavior of programming languages" prof
absolutely guaranteed that C parameters are evaluated left-to-right.
He was a bright guy from CMU whose research focus was on programming
languages, and I believed him, but now I''m not so sure.
Little help?

不要这么肯定是好的：要么他错了，要么你对
他说的是错的。

It''s good not to be so sure: either he''s wrong or your understanding of
what he said is wrong.
