WebApr 13, 2024 · 1. The left-shift and right-shift operators should not be used for negative numbers. The result of is undefined behavior if any of the operands is a negative number. For example results of both 1 >> -1 and 1 << -1 is undefined. 2. If the number is shifted more than the size of the integer, the behavior is undefined. WebIn the C programming language, operations can be performed on a bit level using bitwise operators.. Bitwise operations are contrasted by byte-level operations which characterize the bitwise operators' logical counterparts, the AND, OR, NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits (known as bytes) at …
