import java.io.FileReader;
import java.io.StreamTokenizer;
//from  w  w w.  ja  va  2s  .c  om
public class Main {

  public static void main(String args[]) {

    try {
      FileReader fr = new FileReader(args[0]);
      BufferedReader br = new BufferedReader(fr);
      StreamTokenizer st = new StreamTokenizer(br);

      st.ordinaryChar('.');

      st.wordChars('\'', '\'');

      while (st.nextToken() != StreamTokenizer.TT_EOF) {
        switch (st.ttype) {
        case StreamTokenizer.TT_WORD:
          System.out.println(st.lineno() + ") " + st.sval);
          break;
        case StreamTokenizer.TT_NUMBER:
          System.out.println(st.lineno() + ") " + st.nval);
          break;
        default:
          System.out.println(st.lineno() + ") " + (char) st.ttype);
        }
      }

      fr.close();
    } catch (Exception e) {
      System.out.println("Exception: " + e);
    }
  }
