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.
