The program will be evaluated in this form: ((~x) | x)
i.e. In step1 the complement of X will become
11…..10
and also the value of x will not be updated with the same complement value hence
11…..10
| 00…..01
————–
11…..11
—————
and the value of 111….11 is -1 in two’s complement compiler.
Hence we are getting the value as -1
