WebMar 4, 2024 · Left and right are two shift operators provided by ‘C’ which are represented as follows: Operand << n (Left Shift) Operand >> n (Right Shift) Here, an operand is an integer expression on which we have to perform the shift operation. ‘n’ is the total number of bit positions that we have to shift in the integer expression. WebNov 14, 2024 · 1. 1. 1. The bitwise AND operator is a single ampersand: . It is just a representation of AND which does its work on the bits of the operands rather than the truth value of the operands. Bitwise binary AND performs logical conjunction (shown in the table above) of the bits in each position of a number in its binary form. &.
