            int num2 = 1;

            int Num3;

            Console.WriteLine("Enter number");

            Num3 = Convert.ToInt32(Console.ReadLine());

            Console.WriteLine("Fibonacci number");

            while (num2 < Num3)

            {

                Console.WriteLine(num1);

                num2 = num2 + num1;

                num1 = num2 - num1;

            };

        }
