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 ...
In the C programming language, data types constitute the semantics and characteristics of storage of data elements. They are expressed in the language syntax in form of declarations for memory locations or variables. Data types also determine the types of operations or methods of processing of data elements.
In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.
An especially useful bit operation is count leading zeros used to find the high set bit of a machine word, though it may have different names on various architectures. [1] There's no simple programming language idiom, so it must be provided by a compiler intrinsic or system library routine.
Bits may be accessed individually via the usual indexing notation (A[3]) as well as through all of the usual primitive functions and operators where they are often operated on using a special case algorithm such as summing the bits via a table lookup of bytes. The C programming language's bit fields, pseudo-objects found in structs with size ...
For languages lacking native bit fields, or where the programmer wants control over the resulting bit representation, it is possible to manually manipulate bits within a larger word type. In this case, the programmer can set, test, and change the bits in the field using combinations of masking and bitwise operations .

Although only one bit is necessary to accommodate the value set true and false, programming languages typically implement Boolean types as one or more bytes. Many languages (e.g. Java , Pascal and Ada ) implement Booleans adhering to the concept of Boolean as a distinct logical type.
