WebApr 21, 2004 · Shifting to the Left or the Right. There are two operators: << for shifting a specified number of bits to the left (towards the "high order" bits) >> for shifting to the right. If a shift operation causes some number of bits to go outside of an underlying data type, then those bits are discarded. WebIn the C programming language, operations can be performed on a bit levelusing bitwise operators. Bitwise operations are contrasted by byte-leveloperations which characterize the bitwise operators' logical counterparts, the AND, OR, NOT operators.
