Assuming, integer is 2 byte, What will be the output of the program? |
| Answer» The integer value 2 is represented as 00000000 00000010 in binary system. Negative numbers are represented in 2's complement method. 1's complement of 00000000 00000010 is 11111111 11111101 (Change all 0s to 1 and 1s to 0). 2's complement of 00000000 00000010 is 11111111 11111110 (Add 1 to 1's complement to obtain the 2's complement value). Therefore, in binary we represent -2 as: 11111111 11111110. After left shifting it by 2 bits we obtain: 11111111 11111000, and it is equal to "fff8" in hexadecimal system. | |
