            Console.WriteLine("(1) Centigrade to Farenheit");
            Console.WriteLine("(2) Farenheit to Centigrade");
            Console.Write("\nSelect: ");
            menu = Convert.ToInt32(Console.ReadLine());
            if (menu == 1)
            {
                Console.Write("Enter temperature in Celsius: ");
                temp = Convert.ToDouble(Console.ReadLine());
                fahr = temp * 1.8 + 32;
                Console.WriteLine("Temperature in Fahrenheit = {0:f2}", fahr);
            }
            else if (menu == 2)
            {
                Console.Write("Enter temperature in Fahrenheit: ");
                temp = Convert.ToDouble(Console.ReadLine());
                cels = (temp - 32) * 5 / 9;
                Console.WriteLine("Temperature in Celsius = {0:f2}", cels);
            }
            else
                Console.WriteLine("Invalid selected options");
