namespace sumodd

{

    class sum

    {

        public void sumodd()

        {

            int i;

            int sam = 0;

             

        for (i = 0; i <= 100; i++)

          {

      

              if (i%2 != 0)

              {

            int count = 0;

            sam = sam + i;

            count++;

              }

        }

      Console.WriteLine("sum of 1+3+5+...100 is " + sam);

   

        }

    }
