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

We've explained PHP arithmetic operators, PHP string operators, assignment operators, and today we'll give you a detailed introduction to the PHP operator
"bitwise operator"。
Bit operators are not often used in PHP, but they are still very useful,

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

Bitwise operators allow us to manipulate a single "bit" in the primary data type of an integer, that is, bits. The bitwise operator performs a Boolean algebra on the corresponding bits in the two arguments and eventually produces a result.Bitwise
