Explanation: Representing b1 in binary 8 bits and doing bitwise 1’s complement:
b1(107) 0 1 1 0 1 0 1 1 Value is 107
b2(148) 1 0 0 1 0 1 0 0
After 1’s complement value is 148 on paper
On running the program, as given above, the answer will be 148, otherwise the answer will be −108.
Both the answers are correct but as the left most bit (bit number 7) is 1 in b2, the number will be negative
and the computer has given the answer in 2’s complement form. In order to cross check whether the answer
is correct or not, fi nd out the binary value of 108, which is as follows:
1080 1 101100
Taking 1’s complement ...
