AI Chatbox

I'm making this chatbox project called The Not A Friend Project... Anyway, this project is based on a former chat box, hal. I don't remember the creater, he was on this board a while back and posted his creation. Although, he didn't give source code, so I'm starting from scratch. Here's the source code:

Code:

#include <iostream.h>
#include <stdio.h>
#include <fstream.h>
#include <string.h>
#include <conio.h>
char blank[]=" ";

class mainbot
{
	public:
		mainbot::mainbot();
		~mainbot();
		int userintf();
		int checkinput();
		int checkoutput();
	private:
		char inp[75];
		int inpno;
		char responce[75];
		char inchk[75];
		int inchkcnt;
		char str;
};
mainbot::mainbot()
{
}
mainbot::~mainbot()
{
}
int mainbot::userintf()
{	
	cin.getline(inp,75);
	checkinput();
	checkoutput();
	cout << responce;
	return 0;
}
int mainbot::checkinput()
{
	ifstream input("input.txt");
	input >> str;
	inchkcnt=1;
	while(strcmp(inchk,blank)||!strcmp(inchk,inp))
	{
		strtok(str, inchkcnt);
		inchk=strtok(NULL, inchkcnt);
		inchkcnt++;
	}
	if(!strcmp(inchk,blank))
	{
		cout << "I don't understand." << endl;
	}
	else
	{
		input.close();
		checkoutput();
	}
}
int mainbot::checkoutput()
{
	ifstream output("output.txt");
	output >> str;
	strtok(str, inchknt);
	responce=strtok(NULL, inchknt);
	output.close();
}


int main()
{
	mainbot interf;
	interf.userintf();
	return 0;
}

I've gone through debugging for a while bringing 14 errors down to three:

Code:

E:\Programs\Projects\Tests\Chat Bot\notafriend\nofsource.cpp(45) : error C2664: 'strtok' : cannot convert parameter 1 from 'char' to 'char *'
        Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
E:\Programs\Projects\Tests\Chat Bot\notafriend\nofsource.cpp(46) : error C2664: 'strtok' : cannot convert parameter 2 from 'int' to 'const char *'

They seemed to have either a problem with strtok or with the variables they are taking in. Does anybody know how to solve this? If you see any other problems I may not have picked up, could you post the cures? Thanks.

inchknt

i think should be inchkcnt
now u got 2 errors

Salem, does your code work with these adjustments? Because mine doesn't.

Your compiler is telling you what the problem is. The second parameter to strtok() is expecting a constant character pointer, you are giving it an int!

Example from MSDN...

Code:

/* STRTOK.C: In this program, a loop uses strtok
 * to print all the tokens (separated by commas
 * or blanks) in the string named "string".
 */

#include <string.h>
#include <stdio.h>

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

void main( void )
{
   printf( "%s\n\nTokens:\n", string );
   /* Establish string and get the first token: */
   token = strtok( string, seps );
   while( token != NULL )
   {
      /* While there are tokens in "string" */
      printf( " %s\n", token );
      /* Get next token: */
      token = strtok( NULL, seps );
   }
}

*** EDIT ***

Sorry salem - overlap!

Ok, I've found an in-program error that I narrowed down to here:

Code:

strcpy( inchk, strtok(NULL, blank) );

Salem, I'm using strtok to scan for anything after the checked number. Shouldn't that work? I couldn't think of another way.

I would say in 9 out of 10 instances strtok is the devil. It isn't thread safe and it modifies your variables. Ick! Try strstr or strchr.

On a side note, now comlex of an AI are you planning on making? Making a good AI Chatbot is a pretty complex thing. Do you have a plan for parsing input?

Do you mean chatbot or chatbox? And what is a chatbox?
