WebWhy must a right shift operation be carried out differently for unsigned vs. signed data? Question. Why must a right shift operation be carried out differently for unsigned vs. … WebMar 7, 2024 · For unsigned a and for signed and non-negative a, the value of a >> b is the integer part of a/2 b. For negative a, the value of a >> b is implementation-defined (in most implementations, this performs arithmetic right shift, so that the result remains negative). (until C++20) The value of a << b is the unique value congruent to a * 2 b modulo 2 N
