bitwise XOR operation, since in Qlang engine, ^ is used for get address/pointer of a variable(like & in other engine), so the origin bitwise XOR operator in Golang is used and we will use bitXor function instead. isNil check if a variable equals to nil(especially for non error type ni...

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...
In this tutorial, we will learn how to determine whether a number is even or odd using the Go programming language (Golang). Identifying whether a number is even or odd is a task that demonstrates the use of conditional logic and the modulus operator. We will provide a simple program with...
