WordLinker v.0.5 [Complete Source]

Wow... well this project is finally done. Though it still isn't really, but I'll get to that in a bit....

This project was simply awful. It took me two days to find out why my words weren't printing when I looked up a word to find it's links... low and behold it was because I forgot to put a cout statement there! This is just one example of a whole hosts of simple mistakes compiled with really complex ones that made coding this lil program a living hell. Even now as I'm typing this I still have a headache... so after I post this I'm going to go lie down, but first I wanted to show you what lil bit I did accomplish.

WordLinker v.0.5

It does work. Well it does what it's supposed to do. That is it adds words to the text file... essentially linking them together. This parts works pretty well. There are probably still a few errors, but I haven't found them yet.

Anywho... there is one problem. It only allow you to look up one word, and then it deletes the first letter of your word for every next word you enter... yeh I know beats me too o_O? Anyway here... its quite a bit of code:

Code:

#include <iostream>
#include <fstream>
#include <string>

#define WORD_SLOTS 5000
using namespace std;

bool initialize();
void save();
void start();
void linkWords();
int getWordSlot(char* str);
bool wordExists(char* str);
void findLinks();

class Word
{
      int maxlinks;
      char wordname[50];
      char* links;
      int linkcount;
      
      public:
             Word(char str[]){strcpy(wordname, str);}
             Word(){
                    maxlinks = 1000;
                    links = new char[maxlinks];
                    for(int i = 0; i < maxlinks; i++)links[i] = '\0';
                    strcpy(wordname, "");
                    linkcount = 0;
                    }
             
             void newWord(char* str)
             {
                  strcpy(wordname,str);
             }
             
             char* getWord(){return wordname;}
             
             void addDirLink(char* str)
             {
                  if(linkcount>0)
                  {
                                 links[linkcount] = ' ';
                                 linkcount++;
                  }

                  strcpy(temp, str);
                  //cout<<"temp"<<temp<<endl;
                  for(int i = 0; temp[i]; i++)

I annotated the linkWords function because it works so well, however the other functions should be pretty easy to understand as well. Hope this help someone. Oh and I would really appreciate it if anyone could figure out why the first letter is concatenated when finding links. Thanks

The point is to understand connections between words. Language is one of those things people take for granted, but is actually complex. In fact a lot of things humans find intuitive are extremely complex for a computer program.When you think about it though the human brain is more powerful then a computer and yet it takes us tons of time to figure out simple things. So maybe a lot more processing is going on in our heads then we really give credit for.

Anyway this program is for someone else, and not myself. If I was going about making an A.I. it would not be through human ideas like words, sight, hearing, smell, etc. It would be through computerized versions of that. Such as a my A.I. would naturally be able to sense the limitations of its enviroment. I think the best way to create an A.I. is by programming if for situations mimicking its actual environment, instead of human constructs.

Also about the pointers. I never bother with allocating or deallocating memory for it. maybe I'll care more once I get into asm, and I'll make a GUI when I'm damn good and ready... and or never. TBH this whole thing has been a little bit distracting. It feels too much like a job. I've hardly touched my DirectX book in two weeks, so I think I'm going to give up the project from now on for my own sake.
