WebJan 24, 2024 · The bitwise left shift (<<) operator shifts bits to the left. The left operand is the expression to shift the bits of, and the right operand is an integer number of bits to shift left by. So when we say x << 1, we are saying “shift the bits in the variable x left by 1 place”. New bits shifted in from the right side receive the value 0.
