To perform bit-level operations in C programming, bitwise operators are used. OperatorsMeaning of operators & Bitwise AND | Bitwise OR ^ Bitwise XOR ~ Bitwise complement Shift left >> Shift right Bitwise AND Operator & The output of bitwise AND is 1 if the corresponding bits of two operands...
Swapping two numbers using bitwise operator XOR is a programming trick that is usually asked in technical interviews. It does not use a third temp variable for swapping values between two variables. This solution only works for unsigned integer types. It won't work for floating point, pointers,...
Generally operators work on its operands and give a value as the result. Most of the operators (binary operators) work on 2 operands and a few operators (unary operators) work on a single operand and we have one operator (ternary operator) that work on 3 operands. Similar to mathematics, ...

The logical not operator takes single expression and evaluates to true if the expression is false an evaluates to false if the expression is true. In other words it just reverses the value of the expression.For example! (x >= y) the NOT expression evaluates to true only if the value of...

XOR 运算还会用来做清零操作,任何一个数据和自身进行 XOR 运算结果就为 0,或者做取反操作,只要将一个数据和一个 -1 进行 XOR 就相当于 ~ 操作符号功能。 使用XOR 还可以交换两个变量值,这个很神奇,可以理解为同一个操作数对另一个操作数进行两次连续 XOR 操作值不变,2 ^ 1 ^ 1 还是 2,甚至这个特性是...
