Web2 days ago · When you shift x right by y bits (x >> y), and the highest bit in x is a 1, the behavior depends on the exact data type of x. If x is of type int, the highest bit is the sign bit, determining whether x is negative or not, as we have discussed above. In that case, the sign bit is copied into lower bits, for esoteric historical reasons: WebNoncompliant Code Example (Right Shift) The result of E1 >> E2 is E1 right-shifted E2 bit positions.
