c++ shift undefined behavior

c++ - Why does this loop produce "warning: iteration 3u invokes undefined behavior" and output more 一個全副武裝的老牛仔坐在酒吧裏喝酒,這時一位美女走入坐在他旁邊。稍刻,她轉過頭來問:「你真是牛仔嗎?」「我一生中一直忙於帶領牛群,馴服馬,修圍牆,我想你可以稱呼我為牛仔。」過了一陣子牛仔轉問:「妳呢? 小姐。」「我從未去過牧場,我當然不是牛仔女,我是女同姓戀者。」她繼續:「我一生中一直忙於想女人,由Signed integer overflow (as strictly speaking, there is no such thing as "unsigned integer overflow") means undefined behaviour. And this means anything can happen, and discussing why does it happen under the rules of C++ doesn't make sense. C++11 draft ....

Bitwise operation - Wikipedia, the free encyclopedia有一次坐公車,拿了悠遊卡排隊上車,前面一個人是扔硬幣的,我大腦短路,跟著把悠遊卡扔進去了....鄰居忘了帶鑰匙,從我家陽台翻過去,進到他自家屋裡找到鑰匙後,又從陽台翻出來外面,從外面再打開他自家房門。 更令人叫絕的是,我自始至終在陽台接應著,未覺有不妥之處。 唉!我倆的腦袋肯定被In an arithmetic shift, the bits that are shifted out of either end are discarded. In a left arithmetic shift, zeros are shifted in on the right; in a right arithmetic shift, the sign bit (the MSB in two's complement) is shifted in on the left, thus prese...

The two base variants are the logical left shift and the logical right shift. This is further modulated by the number of bit positions a given value shall...
