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 … WebSep 30, 2024 · BCPL already used ~ for bitwise negation. So from a point of view of consistency, it could have been doubled to give a ~~ to give it its logical meaning. Unfortunately this would have been extremely ambiguous since ~ is a unary operator: ~~b could also mean ~(~b)) .
WebOne's Complement, or Bitwise Negation: ~ The unary operator ~ changes each 1 to a 0 and each 0 to a 1, as in the following example: ~ (10011010) // expression (01100101) // … WebSep 3, 2012 · This operator reverse each bit of an integral type.
