Swaping without Temp Var

[phiras]

Al Salam Alikom
I have 2 integers x&y .
I Want to Swap thos values .
this Code is works very good :

temp = x;
x = y;
y = temp ;

Now you have to do this Operation without Using the temp var ,

GAWD, are you _itching_ for the old XOR trick? can I cheat and use implicit temporaries in function arguments?

int x, y;

void swap (int a, int b)
{
   x = b;
   y = a;
}

[initialize x and y here]

swap (x, y);

are you Keding man ? .
1- Calling the function swap() is creating 2 Vars in the Memory, so it dosn't work.
2- you cn do it with XOR func , but there is another Easy way .
Just think
