Bitwise operations in C Bitwise operations in C In 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 and NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits (known as bytes) at a time. The reason for this is that a byte is normally the smallest unit of addressable memory (i.e. data with a unique memory address.) This applies to bitwise operators as well, which means that even though they operate on only one
Byte (magazine) C, BASIC, assemblers), and coverage of the first microcomputer operating system, CP/M. "Byte" ran Microsoft's first advertisement, as "Micro-Soft", to sell a BASIC interpreter for 8080-based computers. In spring of 1979, owner/publisher Virginia Williamson sold "Byte" to McGraw-Hill. She remained publisher until 1983 and became a vice president of McGraw-Hill Publications Company. Shortly after the IBM PC was introduced, in 1981, the magazine changed editorial policies. It gradually de-emphasized the do-it-yourself electronics and software articles, and began running product reviews. It continued its wide-ranging coverage of hardware and software, but now it reported "what it does" and "how it works",
