Write a program reverse the words in a given string.

    class Program

    {

        static void Main(string[] args)

        {

            int i, j = 0;

            Console.WriteLine("Enter a string ");

            string s = Console.ReadLine();

            Console.WriteLine();

            for (i = 0; i < s.Length; i++)

            {

                if (s[i] == ' ')

                {

                    j++;

                }

            }

            string[] rev = new string[j + 1];

            int t = j;

            for (i = 0; i < s.Length; i++)

            {

                if (s[i] == ' ')

                    j--;

                else

                    rev[j] = rev[j] + s[i];

            }

            for (i = 0; i <= t; i++)

            {

                Console.Write(rev[i] + " ");

            }

            Console.WriteLine();

            Console.ReadLine();

        }

    }
