        {

            //Writes the specified string, followed by the current line terminator, to the standard output stream 

            Console.WriteLine("Please enter first name : ");

            //Reads the next line of characters from the standard input stream

            string first_Name = Console.ReadLine();

            Console.WriteLine("Please enter last name : ");

            string last_Name = Console.ReadLine();

            //print full name using place holder

            Console.WriteLine("Full Name {0} {1}",first_Name ,last_Name);

            // here print full using concatenation string

            Console.WriteLine("Full Name "+first_Name+last_Name);

            Console.ReadLine();
