            //Swapping Occurs Here
            a = a ^ b;
            b = a ^ b;
            a = a ^ b;

            //Printing the Number After Swapping
            Console.WriteLine("Numbers After swapping...");
            Console.WriteLine("a = {0} \t b = {1}", a, b);

            Console.Read();
        }
    }
}

Enter The First Number: 5
Enter The Second Number: 10

Numbers Before Swapping ...
a = 5          b = 10

Numbers After swapping...
a = 10       b = 5
