Integer Encoding Convert the given expressions to 4-bit decimal, 4-bit binary, 6-bit decimal, and 6-bit binary. Use C convention for type casting. Example Expression x = -8. Example solution 4-bit decimal=-8, 4-bit binary = 1000, 6-bit decimal = -8, 6-bit binary 11 1000. (a) x = -5 (b) x = -15 (c) x = -16 (d) x = -37
