Ok I have been working on this code for awhile. So far I set the file to be loaded, I can show a list of the words in the file, but when I choose to add a word it wont save it to the file. I also get this warning not an error:

.\game.cpp(79) : warning C4996: 'strcpy' was declared deprecated
        C:\Program Files\Microsoft Visual Studio 8\VC\include\string.h(73) : see declaration of 'strcpy'
        Message: 'This function or variable may be unsafe. Consider using strcpy_s instead. To disable deprecation, use _CRT_SECURE_NO_DEPRECATE. See online help for details.'

Here is my code in game.cpp:

#include <iostream>
#include <string>
#include <fstream>
#include "game.h"

#define MAX_WORD_SIZE 15
#define MAX_WORDS 255

typedef char String[MAX_WORD_SIZE];
String Words[MAX_WORDS - 1];
int Count;
char Word[MAX_WORD_SIZE];
int Size;
int Loop;

using namespace std;

void Game::loadFile()
{
      char C;
      ifstream Datfile;

      Count = 0;

      Datfile.open("words.txt");

      while((C=Datfile.peek()) !=EOF)
      {
            Datfile >> Words[Count++];

            if(Count > MAX_WORDS - 1)
            {
                  cout << "\nToo many words in the file, stopping with " << MAX_WORDS << " words." << endl;
                  Count = MAX_WORDS;
                  break;
            }
      }

      Count--;

      Datfile.close();
}

void Game::listWords()
{
      Game myGame;
      myGame.loadFile();

      cout << "\tThe following words in the file are: \n" << endl;

      for(int Loop=0; Loop < Count - 1; Loop++)
      {
            cout << "\t" << Words[Loop] << "\n";
            if (++Loop > Count)
                  break;
            cout << "\t" << Words[Loop] << "\n";
            if (++Loop > Count)
                  break;
            cout << "\t" << Words[Loop] << "\n";
            if (++Loop > Count)
                  break;
            cout << "\t" << Words[Loop] << "\n";
            if (++Loop > Count)
                  break;
            cout << "\t" << Words[Loop] << "\n";
      }
}
void Game::addWords()
{
      Game myGame;
      myGame.loadFile();
      ofstream Datfile;

      cout << "\tEnter a new word, keep it below " << MAX_WORD_SIZE << " characters: ";
      cin >> Word;

      Size = strlen(Word);

      strcpy(Words[Count++],Word);

}

Just add "_CRT_SECURE_NO_DEPRECATE" to your project settings under "C++|Preprocessor|Additional symbols".

Or use

      strcpy_s(Words[Count++],MAX_WORD_SIZE,Word);

instead.

To elaborate: MS added this as an extension to ANSI C/C++, since a lot of security holes were caused by buffer overruns that were exploitet maliciously. Note that your code won't be portable unless you set _CRT_SECURE_NO_DEPRECATE.

Seems like you forgot to output it.

You should

void Game::addWords()
{
      Game myGame;
      myGame.loadFile();
      ofstream Datfile;

      cout << "\tEnter a new word, keep it below " << MAX_WORD_SIZE << " characters: ";
      cin >> Word;

      Size = strlen(Word);

      strcpy(Words[Count++],Word);

      for (int i = 0; i < Count; ++i) Datfile << Words[i] << endl;

}

Sorry, that should be

ofstream Datfile("Words.txt");

in the above.
