If the bit in one of the operands is 0 and the bit in the other operand is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0.

WebShift operations are bit-wise operations because we perform these operations on binary value bits of a number. In C++, you can shift a binary number to the left or right using the shift operators << and >>, respectively.
