using System;

namespace FirstName
{
    class MainClass
    {
        static void ReadData(string filename, out string[] Names,
                             out string[] Decade1980, out string[] Decade1990, out string[] Decade2000)
        {
            string input;
             file;

            file = new (filename);

            input = file.ReadLine();        // open file, read first line to get N, parse it:

            int N;
            N = int.Parse (input);
                                    
            Names = new string[N];  // create the arrays:
            Decade1980 = new string[N];
            Decade1990 = new string[N];
            Decade2000 = new string[N];

            input = file.ReadLine();

            for (int i = 0; i < N; i++)
            {
                string[] values;
                values = input.Split ();

                Names [i] = values[0];
                Decade1980[i] = values[9];
                Decade1990[i] = values[10];
                Decade2000[i] = values[11];

                input = file.ReadLine();
            }

            file.Close ();
        
        }





        static void IsNameExist(string word, string[] Names, string[] Decade1980, string[] Decade1990,
                                string[] Decade2000)
        {
            int i;
            i = 0;

            while (i < Names.Length)
            {
                if (Names [i] == word)
                {   

                    Console.WriteLine ("Name: " + Names [i]);
                    Console.WriteLine ("Popularity in 1980: " + Decade1980 [i]);
                    Console.WriteLine ("Popularity in 1990: " + Decade1990 [i]);
                    Console.WriteLine ("Popularity in 2000: " + Decade2000 [i]);
               
                }
                else
                {

                    Console.WriteLine (">> Search failed: " + "'" + word + "'" + "was not found");

                }

            }



        }








        static void Main(string[] args)
        {
            Console.WriteLine ("** Name Popularity Program **");
            Console.WriteLine ();

            string[] Names;
            string[] Decade1980;
            string[] Decade1990;
            string[] Decade2000;

            ReadData ("firstnames.txt", out Names,
                      out Decade1980, out Decade1990, out Decade2000);

            string word;
            Console.Write (">>Please enter a first name to search for: ");
            word = Console.ReadLine ();   

        
            IsNameExist (word, Names, Decade1980, Decade1990, Decade2000);
        
               


            Console.Write (">>Please enter a first name to search for: ");
            word = Console.ReadLine ();

            Console.WriteLine ();
