Код: 
x >> 2 << 2

Что это за хрень?) То-есть сначала сдвигается на 2 бита вправо, потом в лево, и что это даёт? Это не тоже самое, что и х*4/4? Сколько не читаю про эти биты, всё время забываю что они делают :)
 
x=1001//это псевдокод
x>>1
//x==100
x<<1
//x==1000 , в итоге последний знак затерся нулем
 
У меня у одного щас не компилит вот с такой херью?

Я создал эту тему для любых мелких вопросов, что-бы не спамить темами. Суда может кто угодно писать, если что. И эти 2 вопроса разные ;D У них сайт лагал и не могло приконнектиться, уже всё прошло.
