xc [0] = 10;
xc [1] = 1;
printf（"％d"，。i）;
}
输出结果是什么？请详细说明。

很多编译器错误和一些警告，没有修改
如上所述。修好这些之后，在我的一台机器上输出
是167838688，另一台则是1073807626.
严重依赖于实现和机器架构（大
endian / little endian）
再见，Jojo
Lots of compiler errors and some warnings too, without the modifications
mentioned above. After having fixed these, on one of my machine the output
was 167838688, on another it was 1073807626.
Heavily depends in the implementation and machine architecture (big
endian/little endian)
Bye, Jojo

该代码甚至不能与我的编译器一起编译，也不应该与你的编译器一起编译。在将代码提交到此新闻组之前，您至少应该努力确保代码编译成
。否则，
这里的任何人都很难为你提供帮助。
祝你好运

That code does not even compile with my compilers and should not
compile with yours. You should at least make an effort to insure that
your code compiles before submitting it to this newsgroup. Otherwise,
it can be difficult for anyone here to provide help to you.
Best regards

非常感谢！我的程序有问题，因为你在右边修正了
。
#include < stdio.h>
union un
{
int I;
char c [2];
}
int main（无效）
{
union un x;
xc [0] = 10;
xc [1] = 1;
printf（"％d"，。i）;
printf（"％d \ n"，xI）;
返回0;
}
Thank you very much!I have something wrong with the procedure, as you
corrected by the right .
#include <stdio.h>
union un
{
int I;
char c[2];

int main(void)
{
union un x;

然而，我仍然不知道如何编译原理，为什么数字
输出？取决于每个输出的结果有何不同？
However, I still do not know how the compiler theory, Why the digital
output ? Depends what the outcome is different for each output?
