C# programming

Question

Hi,

Write an algorithm to swap the values of two variables without using a third variable.

Answer 1

Here's another way of doing it:

      int i = 1;

      int j = 2;

      i ^= j;

      j ^= i;

      i ^= j;

      Console.WriteLine("i = {0}, j = {1}", i, j);

Answer 2

  Something like this, try it..

            int i = 1;

            int j = 2;

            Console.WriteLine("i = " + i);

            Console.WriteLine("j = " + j);

            i = (j + i);

            j = (i - j);

            i = (i - j);

            Console.WriteLine("");

            Console.WriteLine("i = " + i);

            Console.WriteLine("j = " + j);

            Console.ReadKey();
