Consider the representation of six-bit numbers by two's complement, one's complement, or by sign and magnitude: In which representation is there overflow from the addition of the integers 011000 and 011000 ?

Question

TestUstad · Accepted Answer

All three representations. In all three six-bit signed representations, 011000 represents +24, so adding it to itself gives +48, outside the representable positive range. Therefore overflow occurs in two's complement, one's complement, and sign-and-magnitude representations.
