{

    class Simple12   //reverse a number

    {

        static void Main(string[] args)

        {

                Console.Write("Enter a number: ");

                int n = Convert.ToInt32(Console.ReadLine());

                int r = 0;

                int rev = 0;

                int temp = n;

                if (n > 0)

                {

                    Console.WriteLine("Reverse of {0} is: {1}", temp, reverseLogic(n, r, rev));

                }

                else

                {

                    n = n * -1;

                    Console.WriteLine("Reverse of {0} is: -{1}", temp, reverseLogic(n, r, rev));

                }

                Console.ReadKey();

           

        }

        public static int reverseLogic(int n, int r, int rev)

        {

            for (; n > 0; )

            {

                r = n % 10;

                rev = rev * 10 + r;

                n = n / 10;

            }

            return rev;

        }

    }

}

Output:

The input number is 456. The program will reverse the input number. The output is shown below:
