Bitand c++
WebJun 15, 2015 · Unfortunately, macros can't expand recursively. When a macro expands, it can become painted blue, which prevents it from expanding anymore. First, there are ways to work around this to prevent macros from being painted blue. Secondly, we can detect if a macro is painted blue (because it wont expand) and use this state to expand to a different ... 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, 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 …
