问题描述

是否可以通过编写C程序来了解系统是小端还是大端

？如果有的话，有人可以给我一个想法吗？

方法...


非常感谢。


问候，

Raghu

Is it possible to know whether a system is little endian or big endian
by writing a C program? If so, can anyone please give me the idea to
approach...

Thanks a ton.

Regards,
Raghu

如果你小心，它可能无关紧要。

是的。

Yes.

是的。甚至有些人甚至可以运用诗意的许可证，并将你的回答改为：b / b
如果你真的很小心，它可以保证没关系。

Yes. And some might even exercise poetic license and rephrase your
answer to something like this:

If you''re really carefull, it''s guaranteed for it not to matter.

字节序的本质是当你使用
访问两种不同大小的对象的地址。当您获取较小的对象时，你会获得更大的

对象的大端还是小端？


In C，你可以合法地将任何对象视为一个字节序列，所以你可以确定b
$ b可以确定端点（尽管它不能保证

要么大 - 或者小端 - 它可能是一些陌生的东西。）

应考虑在一些字母表中需要多达32个字符

- 1963年的X3.4。

The essence of endianness is the question of what happens when you use
an address to access objects of two different sizes. When you fetch
the smaller object, do you get the big end or the little end of larger
object?

In C, you can legally treat any object as a sequence of bytes, so you
can indeed portably determine the endianness (though it''s not guaranteed
to be either big- or little-endian - it could be something stranger).
