Answer / muzammil

Here are some LOGICS to swap two nmbrs

1) a+=b; b=a-b; a-=b;
2) a*=b; b=a/b; a/=b;
3) a=a^b; b=a^b; a=a^b;

Now Single line statements

4) a=a-(b=(-b+(a=a+b)));
5) a=a^(b=(b^(a=a^b)));
6) b=a+b-(a=b); This one was posted BY Senthil Thanks to him
7) b=a*b/(a=b); Dis is same as above one except for da
operators.
