问题描述

请帮助我..........................

以下声明的输出是什么？和为什么

i = 0;

printf（"％d％d％d"，++ i，i，i ++）;

<函数printf中的div class =h2_lin>解决方案

从右到左。

所以我们可以得到输出：2 1 0

以下声明的输出是什么？以及为什么

i = 0;

printf（" ;％d％d％d"，++ I，I，I ++）;

未定义，因为i的值被多次修改

序列点之间。

你完全错了。任何查看常见问题解答或关注

新闻组的人（在发布到任何新闻组之前的两个关键做法）都会知道这两行中没有定义的输出，并且会

知道没有理由期望对

参数进行评估。


但人们期望得到什么？使用Gmail的顶级海报？

Its undefined because the value of i is modified more than once
between sequence points.

You are simply wrong. Anyone who checked the FAQ or followed the
newsgroup (two crucial practices before posting to any newsgroup) would
know that there is no defined output from those two lines, and would
know that there is no reason to expect right to left evaluation of
arguments.

But what does one expect of a top-poster who uses gmail?
