        {
            Console.WriteLine("\n\t\tPrint fibonacci series 0 1 1 2 3 5 8 13 ...\n\n");
            Console.Write("\n\t\tEnter range of terms of fibonacci series : ");
            n = Convert.ToInt32(Console.ReadLine());
            Console.Write("\n\t\tFirst {0} terms are : ", n);
            for (int x = 0; x < n; x++)
            {
                if (x <= 1)
                { fib = x; }
                else
                {
                    fib = f + s;
                    f = s;
                    s = fib;
                }
                Console.Write("{0} ", fib);
            }
