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 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
in C #, you can perform a bitwise logical operation on an integer operand. The meaning of the bitwise logical operation is that each bit of the operand is taken sequentially, and the logical operation of each bit is the result of each bit of the
