About LinkBacksi want to reverse the bits of unsigned number by using bitwise operatores ( & , | , ^ , ~ , << , >> ) , i am working in borland C++
example :
00110101 -> 10101100
please help me if u can .....

xor doesn't help much for reversing. it's better used for inverting.Originally Posted by backtolife

7. It is easier to write an incorrect program than understand a correct one.
40. There are two ways to write error-free programs; only the third one works.*
I would use &, |, << and >>, or perhaps their assignment variants.Use exclusive or.

Start by showing us a program which uses & and >> in a for loop to print each bit in turn.
If you then use << on that bit, you might be onto something.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
