Using a 5-bit two\'s complement system, set up below the sum +15 + (-16). Do it!! Interpret the answer in decimal: Which of the following ALU flags would be set to a \"1\" by this addition?

Solution

15->01111

-16->10000

15+(-16)=11111=>-1

V -> No over flow (false)

C-> Carry flag (false) because no carry

N->negative flage true, as -1 is the result

Z-> Zero flag flase
