What is Bitwise Operator?
Definition and meaning of Bitwise Operator
A bitwise Operator is an operator used to perForm bitwise operations on bit patterns or Binary numerals that contain the manipulation of individual bits.
Bitwise Operators are used in:
- Communication Stacks where the individual bits within the Header connected to the Records symbolize vital information
- Embedded Software program for conTrolling extraordinary capabilities inside the Chip and indicating the fame of Hardware by way of manipulating the Character bits of hardware registers of embedded Microcontrollers
- Low-stage Programming for applications inclusive of tool drivers, cryptographic Software, video deCiphering software, Memory allocators, compression Software Program and pix
- Maintaining huge uNits of Integers effectively in search and optimization issues
- Bitwise operations finished on bit Flags, which can allow an example of Enumeration type to shop any mixture of values described in an enumerator list
What Does Bitwise Operator Mean?
Unlike commonplace logical operators (like , -, *), which paintings with bytes or organizations of bytes, bitwise operators can test or set every of the man or woman bits within a byte. Bitwise operators in no way purpose overflow due to the fact the end result produced after the bitwise operation is inside the Range of possible values for the numeric type concerned.
The bitwise operators used inside the C family): Result is genuine if any of the Operands is genuine.
AND (&): Result is authentic simplest if both operands are genuine. It can be used to set up a mask to check the values of certain bits. XOR (^): Result is proper most effective if one in every of its operands is genuine. It is used in particular to Toggle certain bits. It also allows to cHange two Variables with out the use of a 3rd one. Bitwise Complement or Inversion or NOT (~): Provides the bitwise complement of an operand through inverting its cost such that every one zeros are was ones and all ones are turned to zeros. >> (Right-Shift) and << (Left-Shift) Operator: Moves the bits the number of positions precise by means of the second operand in the proper or left path. While the proper-shift operation is an mathematics shift for operands of type int or lengthy, it is a logical shift for operands of type uint or ulong. Shift operators are used in aligning bits. The order of priority (from highest to lowest) in bitwise operators is:
- ~
- << and >>
- &
- ^
