bitwise mask

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

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 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 their usage

1. bitwise and operation bitwise AND operator "&" are binary operators. Its function is the binary phase corresponding to the two numbers involved in the operation. The result bit is 1 only when the two binary numbers are 1. Otherwise, the result

UVA 10718 Bit MaskIn bit-wise expression, mask was a common term. You can get a certain bit-pattern using mask. For example, if your want to make first 4 bits of a 32-bit number zero, you can use 0XFFFFFFF0 as mask and perform a bit-wi SE and
