Obviously 1000 right shifted with sign is 1100 which is your -4 (in 2's complement form). I think you just copied the comments over and forgot to change them.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-37345047608068054372013-10-11T14:57:05.809-07:002013-10-11T14:57:05.809-07:00The ~ of int 2 should be more like 111111111111111...The ~ of int 2 should be more like 1111111111111111111111111111101 not 1101 or -3 as you say since ints are 32 bit.
