1. cBitwise operators in languages
Because the C language is designed to replace the assembly language, it must support the computing power of the assembly language, so the C language supports all bitwise operators ). Bit operations are used to test,
C # basic usage of bitwise operators,
Bitwise operators include: | bitwise OR, & bitwise AND, ^ bitwise xor or xor ,~ NOT, Right Shift, and so on. This article describes the application of the bitwise operator in C. It mainly includes:

In this article, let's take a look at the objective-c bitwise operator . There are various operators in the objective-c language to handle the special positioning in numbers, as shown in the following table:

Bitwise operators include: | bitwise OR or, & bitwise AND and, ^ bitwise XOR or XOR ,~ Not, right shift, and so on. This article describes the application of the bitwise operator in C. It mainly includes:

InC ProgrammingIn, the bit of data is the smallest unit of data that can be operated. In theory, you can use the bitwise operation to complete all the operations and operations. AverageBit operationIt is used to control hardware or perform data
Language bitwise operators: With, OR, XOR, reverse, move left, and rightA bitwise operation is a binary-based operation. In system software, it is often necessary to deal with bits problems. The C language provides 6 bit manipulation operators.
Bitwise operatorsC provides six bitwise operators. These operators may only allow integer operands, namely char, short, Int, and long, regardless of signed or unsigned.& By-bit and| Bitwise OR^ Bitwise OR> Right shift~ Inverse (unary

Bitwise operators are very low-level operations and are not commonly used because they are not intuitive. However, its speed is very fast, and reasonable use can achieve very good results. This article will introduce the operator-bitwise
Bitwise operators allow you to evaluate and manipulate the bits specified in the integer number.
Bitwise operators
Example name result
$a & $b and (bitwise AND) will set the 1 bit in the $a and $b to 1.
$a | $b or (bitwise OR) sets any bit in the
