int a=10,b=20; a=a*b; b=a/b; a=a/b; I think jignesh's first ans is best instead of using arithmatic operators.

hi, you may use bitwise exclusive or operator to swap two number example. int x = 10; int y = 12; x ^= y; y ^= x; x ^= y; you may also swap string without use third string string a = "jignesh"; string b = "Trivedi"; a += b; b = a.Substring(0, a.Length - b.Length); a = a.Substring(b.Length); hope this will help you.
