Do not assume that a right shift operation is implemented as either an arithmetic (signed) shift or a logical (unsigned) shift. If {{E1}} in the expression {{E1 >> E2}} has a signed type and a negative value, the resulting value is implementation -defined and may be either an arithmetic shift or a logical shift. Also, be careful to avoid undefined behavior while performing a bitwise shift \[[INT36-C. Do not shift a negative number of bits or more bits than exist in the operand]\]. |
