Question

1. [10] Given the declarations: signed char x = 0x05, y = 0x0A, z = 0x2F; // we are using 1 byte = 8 bits Evaluate each of the following. Give the answers as two hexadecimal characters a) -9 b) x - y c) x \^ y d) (x << 2) & z e) (x \^ y) | (~z) 2. [10] Suppose we are using a machine with that uses 7 bits to store a float value with 3 bits for the exponent, in the manner of the IEEE 754 standard. (Hint: the bias would be 3) Do either: Decode: 1100110 OR Encode 3.25$_{10}$ Circle your choice, show work below.
