這明顯用Tries就可以輕鬆完成, 可是我卻卡在讀取那邊...

  int n, cnt;
  int i, j, tmp;
  char c[]; 
  int s[];  

  while ( scanf ( "%d", &n ) != EOF )
  {
    memset ( s, 0, xxxxxx*sizeof(int) );
    cnt = 0;
    for ( i = 0; i < n; i++ )
    {
      scanf ( "%s", c );
     
      tmp = 0;
      for ( j = 0; j < 4; j++ )
       
      if (  )
      {
        printf ( "New! %d\n",  );
      }
      else printf ( "Old! %d\n", );
 
    };
  };

奇怪的是我將同樣的code轉成pascal就過了, 這讓我非常苦惱...

var i, j, n, tmp, cnt : longint;
    s : array [ 0 .. xxxxxx ] of longint;
    c : string;

begin
  while not eof do
  begin
    readln ( n );
    cnt := 0;
    fillchar ( s, xxxxxx*sizeof(longint), 0 );
    for i := 1 to n do
    begin
      readln ( c );
      tmp := 0;
      for j := 1 to 4 do

      if (  ) then
      begin

        writeln ( 'New! ',);
      end
      else writeln ( 'Old! ', );
    end;
  end;
end.

想請教一下我C++的code哪裡出問題了? 謝謝
