问题描述

我在网上有一个小程序...但是我看到了不同的初始化

...


如下：


for（i =〜0; i; i>> = 1）;


右移是好的..但是什么是meaned通过 i = ~0" ...

I got a small programm on net...but there was different initialisation
that I saw...

It was as follows:

for ( i = ~0 ; i ; i>>=1);

right shift is ok..But what is meaned by " i = ~0 "...

Tilde是一个补码运算符。我不认为这是一个防弹代码，结果可能与一个人的补充价格不同，而不是两个补码。机。结果是

负零在一个人的补充机器上。

Tilde is the one''s complement operator. I would not think of that as
bulletproof code, the results might well be different on a one''s complement
machine than they are on a two''s complement machine. The result is
"negative zero" on a one''s complement machine.

它如下：

（i =〜0; i; i>> = 1）;

右移是正确的。但是什么是 i = ~0" ...

It was as follows:

for ( i = ~0 ; i ; i>>=1);

不在1'的补码或签名的机器上。
