Bit shift operators c

WebJun 25, 2009 · @JoshC: (cont.) And in C, the bit shift operators are defined in a way that abstracts them even more: they are defined in terms of the values they produce, not in terms of the way they move the underlying bits around (so if you're on some obscure platform where a hardware bit-shift instruction would produce an invalid bit layout, e.g. you've … WebAn integer is usually 32-bits or 64-bits long, for example. An important thing to keep in mind is that shifting by 1 to the left is the same as multiplying by 2, while shifting to the right by 1 is the same as dividing by 2 then rounding down. C doesn't have a >>> operator, and shifting of negative numbers is undefined in C.
