Question

Write the following 4-byte integer values in binary or hexadecimal a. 3 b. 14 c. -1 d. The largest unsigned integer. e. The most negative signed integer. Please write a C function int counterOflsBits(unsigned int u) that returns the number of bits in u that are 1. Examples: counterOf 1 sBits [0x00000000] = 0 counterOflsBits[0x00000001] = 1 counterOflsBits[0x00000002] = 1 counterOflsBits[0x00000004] = 1 counterOflsBits[0x00000008] = 1 counterOflsBits[0x00000010] = 1 counterOflsBits[0x00000020] = 1 counterOflsBits[0x00000040] = 1 counterOflsBits[0x00000003] = 2
