bitwise power of 2

Front. 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

1.bitwise logical Non-arithmetic ~A bitwise logical non-operation is single-purpose, with only one operand. Bitwise logical non-operation bitwise pairs the value of an operand into a non-operation, i.e. if one is equal to 0, it is converted to 1,

    Summary   Bitwise operations are one of the basic operations in C/C ++. Even so, it is a strange operation for most programmers-most programmers seldom use bitwise operations. This article first briefly introduces the basic bitwise operators and

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:   ○

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,

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:   ○ Hexadecimal conversion※Convert

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
