XOR Magic Function

#define swap(x,y) (x^=y^=x^=y)

This magical single line can swap two number Do you want to know how it works just read

following

example code:

#include<stdio.!


"ain()

int a=$,%=&'

swap(a,%)'

pintf(*d *da,%)'

+

Output & $

Do you hert about XOR fonction here i am showing simple xor table for and !

-/01 O01/01

2 3 Result(2 XOR 3)

! !

! !

-"p pop 4"are it is clear that when both input a and b are same output will be zero

l"p pop 5 XOR of any non zero and zero is always e#uals to that non zero number$char%

-"p pop $ 6 we use ^ symbol for make XOR of any to functions

if you understand ! and & properties ypu can easily understand 'agical function

(s you may be know

()*&+

,t gi-es (*()&+

hare ) is a operator now . is also a operator so

X.*/+ returns X*X./+

now look at 'acro


now on splitting it gi-es

!% x*x.y

&% y*y.x

0% x*x.y

for example let x=3 and y= 5 so x^y=6

pass zero

x=3 y=5

pass first x consist XOR of x any y



x=3^5 y=5

pass second y * y.x1hare x* x.y from pass !2 * y.x.y

x=3^5 y=5^3^5

from prop ! y.y *

x=3^5 y=3^(5^5)

As 5^5=0

y=3^0

from prop & x. * x

y=3

so y consists x

pass third x*x1hare x* x.y from pass !2.y1hare y*x from pass &2

x=3^5^3 y=3

x* x.y.x on using prop !

x=5^(3^3)

x=5^0

on using prop &

x=5

now x consists y

swapping done successful
