以下是全文，我觉得你把你的想法发给他们，是不是就能得到面试？？你试试吧，我知道得也就这么多。发个帖子解解闷..
栈溢出应该是对的，我想他们肯定是找C和汇编的高手，起码能用softice之类的软件把跟踪过程跟他们讲清楚才行。

SAMPLE QUIZ QUESTION:


If you can correctly answer the following, you are guaranteed an
interview:


Why does the following program output a 0? Explain in detail.


#include <stdio.h>
#include <string.h>
int main(int argc, char *argv[])


{
int i = 1;
char buf[4];
strcpy(buf, "AAAA");
printf("%d\n", i);
return 0;

[大岭]

输出不一定是0, 可能是1.

[hcf_15]

You got 0, because you used MS C/C++ on Windows.
You will get 1 on Unix, I am prefer sure. Have you tried compiled by Borland? Probably it is 1 too.

1) i is pushed into stack before buf array;
2) number 1 is stored as 01 00;
3) strcpy stores '\0' to buf[4], i.e. the lower byte of i
