Chapter 2, Problem 2.63HW

Fill in code for the following C functions. Function srl performs a logical right shift using an arithmetic right shift (given by value xsra), followed by other operations not including right shifts or division. Function sra performs an arithmetic right shift using a logical right shift (given by value xsr1), followed by other operations not including right shifts or division. You may use the computation 8*sizeof (int) to determine w, the number of bits in data type int. The shift amount k can range from 0 to w – 1.'

unsigned srl(unsigned x, int k) {

/* Perform, shift arithmetically */

unsigned xsra = (int) x >> k;

int sra(int x, int k) {

/* Perform shift logically */

int xsrl = (unsigned) x >>k;
