deleting words from a file... cant save the output

I am having issues with saving the output for my code here is my delete code.

void Game::deleteWords()
{
      myGame.loadFile();
      ofstream Datfile("words.txt");

      cout << "\tEnter a word to remove from list: ";
      cin >> Word;

      Size = strlen(Word);

      for(Loop = 0; Loop < Count; Loop++)
      {
            if(strcmp(Words[Loop],Word) == 0)
            {
                  strcpy_s(Words[Loop],MAX_WORD_SIZE,Words[--Count]);
                  strcpy_s(Words[Count], "");
                  break;
            }
      }
    for (int i = 0; i < Count - 1; i++) Datfile << Words[i] << endl;
}
