(For left shifts things are even worse, the result for -ve values is undefined.) So, it … WebApr 15, 2024 · This function has completely defined behaviour for logical right shift given that the value of n is within the limits (non-negative and less than the width of x in bits): unsigned int logicalShift(unsigned int x, int n) { return x >> n; } As it does one expression only, we notice that using a function for such an operation is not needed.
