            int temp;

            Console.WriteLine("Type value of number 1 :");
            num1 = Convert.ToInt32( Console.ReadLine());
            Console.WriteLine("Type value of number 2 :");
            num2 = Convert.ToInt32(Console.ReadLine());

            temp = num1;
            num1 = num2;
            num2 = temp;

            Console.WriteLine("\nAfter swapping values");
            Console.WriteLine("Value of number 1 : "+ num1);
            Console.WriteLine("Value of number 2 : "+ num2);
            Console.ReadKey();
        }
