Smarterchild

I just had a crazy idea to make a simple smarterchild type talking robot. All it does is remember your name and say hello...stuff like that...and then you can ask Do you know....and he will search his Database for any knowledge of that topic and if he doesn't know then he asks you to tell him so he can recall the knowledge. I think that will require the use of file i/o....any helpful hints on coding?

Start doing it... ?

What kind of hints do you want? You know what you want to make and you have an idea on how you want to make it. So get where you can and when you run into an issue, tell us about it. What you told us is so general, I wouldn't know where to begin with hints. Be efficient... indent... be modular... I don't know what else to say.

Oh... and give it X-ray vision and the strength of five gorillas.

Yeah, I am in a very blank mood today!

It has a problem in the underlined line...parse error...any help?

You have code that looks like this:

Code:

---

if(x) {}
else {}
else if(x) {}

---

Work on your indentation.

I know that that is where the problem lies but I'mnot sure how to rectify it!

Code:

---

} while ( keepgoing = 1 );

---

->

Code:

---

} while ( keepgoing == 1 );

---

That doesnt solve my problem though

You need an extra closing brace (}) before your underlined else.

Work on your indentation. If it was indented properly you'd see the problem immediately.

Thanks...yes I know my indenting is poor but its a work in progress

Code:

---

    do {
        cout<<endl;
        cout<<name<<"'s says: ";
        getline (cin, question);
        cout<<endl;

            cout<<"What do you want to know?"<<endl;
            cout<<endl;
            cout<<name<<"'s says: ";
            getline (cin, subject);
            cout << endl;  /* this used to be "endl" */
            file = subject + ".txt";
            ifstream c_file ( file.c_str() );
            if (!c_file.is_open()) {
                cout<<"Sorry I do not know what "<<subject<<" is."<<endl;
                cout<<endl;
                cout<<"Please enter a definition of "<<subject<<"."<<endl;

Doesn't that look better?

My changes are in bold.

I haven't made those changes because I don't have time, however I ave a problem where it will only read the first word from the file.

Code:

---

if ( question == "do you know?" ) {
        cout<<"What do you want to know?"<<endl;
        cout<<endl;
        cout<<name<<" says: ";
        getline (cin, subject);
        endl;
        file = subject + ".txt";
        ifstream c_file ( file.c_str() );
              if (!c_file.is_open()) {
              cout<<endl;
              cout<<"Sorry I do not know what "<<subject<<" is."<<endl;
              cout<<endl;
              cout<<"Please enter a definition of "<<subject<<"."<<endl;
              cout<<endl;
              cout<<name<<" says: ";
              getline (cin, response);
              endl;
              ofstream d_file ( file.c_str() );
              d_file<<response<<endl;
              d_file.close();
              cout<<endl;
              cout<<"Thank you! I now know what "<<subject<<" is."<<endl;
              cout<<endl;
              cout<<"How about another question!"<<endl;
              keepgoing = 1;
              }
              else {
              cout<<endl;
              c_file>> response;
              cout<<response<<endl;
              cout<<endl;
              cout<<"There you go! Thats all I know about "<<subject<<"!"<<endl;
              cout<<endl;
              cout<<"So let's get on to the next question..."<<endl;
              keepgoing = 1;
              }

its in there somewhere

It is meant to save the information about the subject to a file and then if you ask about that subject again...it will give the definition..however it only reads the first word og teh definition e.g full definition = a loose fitting t-shirt

all it will say is

a

Code:

---

ifstream load("file.dat");

load >> string1;
load >> string2;
load >> string3; // this will read 3 words with spaces. But you'll have to know the number of words!

---

Its an undefined number of words that I will be using

This:

Code:

---

endl;

---

should be

Code:

---

cout << endl;

---

as you would have seen if you'd read my post. endl by itself doesn't do anything, as a compiler with warnings on will tell you. :)

Quote:

---

Its an undefined number of words that I will be using

---

I would suggest a vector of strings, or just a for loop printing each string individually.

eg

Code:

---

while(getline(file, line)) cout << line;

---

How would I use that in my code...I do not have a vast enough knowledge to be able to solve my problems?

Anybody?

...if you can't figure out where/how to place that code, I really don't think you're ready for a dip in the AI pool...

I got bored and wrote this up real quick:

Code:

---

#include <iostream>
#include <string>

void capitalize(std::string &input);

int main()
{
        std::string input;
       
        std::cout<<"Hello. I am testBot.  Please reply with an empty line\n"
                <<"to end our conversation\n> ";
        while(getline(std::cin,input,'\n'))
        {
                capitalize(input);
                //std::cerr<<"::"<<input<<std::endl;
                if(input=="HI" || input=="HELLO" || input=="HEY" || input=="YO")
                {
                        std::cout<<"Hello, how can I help you today?\n> ";
                }
                else if(input.substr(0,3)=="WHO")
                {
                        if(input.substr(4,4)=="MADE" ||
                          input.substr(4,5)=="WROTE")
                        {
                                std::cout<<"I was written by Major_Small\n> ";
                        }
                }
                else if(input=="" || input=="BYE" || input=="GOODBYE" ||
                        input=="LATER" || input=="NIGHT" || input=="GOODNIGHT")
                {
                        std::cout<<"Good bye for now."<<std::endl;
                        break;
                }
                else
                {
                        std::cout<<"Sorry, I could not recogize your accent\n> ";
                }
        }

        return 0;
}

void capitalize(std::string &input)
{
        std::string temp=input;
        register short int l;
        register short int r;
       
        for(l=0,r=input.length()-1;l<=r;l++,r--)
        {
                temp[l]=toupper(input[l]);
                temp[r]=toupper(input[r]);
        }

        input=temp;
}

that's not a very useful/scalable example, so I wouldn't use it (and besides, if you ask it who wrote the declaration of independence, it just tells you who wrote the bot), but there are some things you can take away from it... like how there are different ways to say hello/goodbye/etc, and how people capitalize differently, and a whole host of different things like what if somebody forgets a space or their english isn't the best? what about the differences from "howdy/hello/hi/hey there/what up/hai2u/etc."

you may want to write a file with questions and responses and use a scoring system or something. for example, have "who/wrote/made/created/you/this/bot" as something to check the input against and have "I was created by me" as the response to that. Now check the input sentence for the words and give that answer a score. the response with the highest score gets output.

These ideas are all my own, and to be honest, I don't know a whole lot about AI programming, so you'd probably be better off asking somebody else, but like I said, just look at the code and take note of some of the pitfalls you'll want to look into getting over...

I wasnt really attempting AI, all it needs to do is read from a file..which it obviously can't do without being an uberwizkid of doom

no, you want it to read from a file and decide what to output based on it's input... at it's core, that's what AI is all about - it recieves input, and makes a decision on what to output dependant on that input.

and to open and read from a file:

Code:

---

#include <iostream>
#include <fstream>

int main()
{
        std::fstream file("test.dat",std::ios::in);
        //now you have a stream called 'file' you can read from, just like cin
        file.close();
        file.clear();
        return 0;
}

---

> I haven't made those changes because I don't have time,
No, but you do have time to wait several hours for someone else to format the code for you just to find your own mistakes, whereas doing the job yourself would teach you a thing or two and take only 5 minutes at most :rolleyes:

Decent formatting from the outset makes those kinds of bugs impossible to begin with. It is not an afterthought you do at the end of the task just to earn extra brownie points.

I actually spent ages finding loads of stupid errors in that code...major_small...does that code code read the whole of the file?

I love ambiguous questions - yes it can read the whole file, and here's how:

Code:

---

#include <iostream>
#include <fstream>

int main()
{
        std::fstream file("test.dat",std::ios::in);
       
        //here we start reading the file
        struct words;
        struct words
        {
                char ch;
                words*link;
        } *head,*curr,*next;

        head=new words;
        curr=head;
        next=0;
        head->ch='\0';

        while(file.get(curr->ch))
        {
                next=new words;
                curr->link=next;
                curr=next;
                curr->ch='\0';
                curr->link=0;
        }

        //now we've read the whole file and can close it
        file.close();
        file.clear();

        //here we're writing the file to the console from memory.
        curr=head;
        head=0;
        while(curr)
        {
                std::cout<<curr->ch;
                next=curr->link;
                curr->link=0;
                delete curr;
                curr=next;
        }
        return 0;
}

:D

I give up!

I am useless :(

you need to be able to tell us where you want to go before we can help you get there.

you wanted me to read the whole file for you, and I did ;)

The problem I have is that after I type in the definition of the subject as a string...it outputs to a file. Then in later life if I want it to tell me what the definition is...it reads the file and the prints it on teh screen, however it will only read the first word of the string.

well, what does your file and read look like right now?

Code:

---

do {
      cout<<endl;
      cout<<name<<" says: ";
      getline (cin, question);
      cout<<endl;

        if ( question == "do you know?" ) {
        cout<<"What do you want to know?"<<endl;
        cout<<endl;
        cout<<name<<" says: ";
        getline (cin, subject);
        endl;
        file = subject + ".txt";
        ifstream c_file ( file.c_str() );
              if (!c_file.is_open()) {
              cout<<endl;
              cout<<"Sorry I do not know what "<<subject<<" is."<<endl;
              cout<<endl;
              cout<<"Please enter a definition of "<<subject<<"."<<endl;
              cout<<endl;
              cout<<name<<" says: ";
              getline (cin, response);
              endl;
              ofstream d_file ( file.c_str() );
              d_file<<response<<endl;
              d_file.close();
              cout<<endl;
              cout<<"Thank you! I now know what "<<subject<<" is."<<endl;
              cout<<endl;
              cout<<"How about another question!"<<endl;
              keepgoing = 1;
              }
              else {
              cout<<endl;
              c_file>> response;
              cout<<response<<endl;
              cout<<endl;
              cout<<"There you go! Thats all I know about "<<subject<<"!"<<endl;
              cout<<endl;
              cout<<"So let's get on to the next question..."<<endl;
              keepgoing = 1;
              }
              }
        else if ( question == "who are you?" ) {
        cout<<"I am Smarterthanchild, the world's only completely"<<endl;
        cout<<"useless talking robot and hopefully there are many"<<endl;
        cout<<"in development"<<endl;

        keepgoing = 1;
        }
} while ( keepgoing == 1 );

That is the bit with the main problems....it is probably very messy coding wise

okay, I reformatted your code and got rid of the syntax errors for you. and if you ever mix spaces and tabs again I'll have to hire an assassin.

edit: some of the changes you should notice right away (I don't even remember all the changes I made)

• better formatting (all tabs)
• slightly more efficient code (no need to call endl for every newline)
• changed keepgoing to a boolean variable

edit2: it's dinner time, so I can't work on it right now, but the first thing that catches my attention is that you're opening the file for writing without any mode flags. Probably not your main problem, but definately not a good idea.

Are the flag things that you mean things like ios::app?

Any help?

You're not supposed to bump threads.

Yes.

I was thinking about how to solve my problems at school today...is it possible to read into a character array to find out how long it is? Because I thought of character array [x]...get the input....find the length save x and save the array?

Would that wor and how can I implement that in what I have

Daved asked for example code...I have none...but what I want is for the user to input a phrase...it is then saved as a text file and can then be recalled when the subject is requested...I have it workign using strings apart from it will only read the first word of teh saved string

just read in until you get a newline character

Code:

---

file.getline(array,maxsizeofarray,'\n');

Makes it difficult to help you without code.

Makes it difficult to be working without code. How'd you accomplish this feat?

Here is the part with problems:

Code:

---

do {
      cout<<endl;
      cout<<name<<" says: ";
      getline (cin, question);
      cout<<endl;

        if ( question == "do you know?" ) {
        cout<<"What do you want to know?"<<endl;
        cout<<endl;
        cout<<name<<" says: ";
        getline (cin, subject);
        endl;
        file = subject + ".txt";
        ifstream c_file ( file.c_str() );
              if (!c_file.is_open()) {
              cout<<endl;
              cout<<"Sorry I do not know what "<<subject<<" is."<<endl;
              cout<<endl;
              cout<<"Please enter a definition of "<<subject<<"."<<endl;
              cout<<endl;
              cout<<name<<" says: ";
              getline (cin, response);
              endl;
              ofstream d_file ( file.c_str() );
              d_file<<response<<endl;
              d_file.close();
              cout<<endl;
              cout<<"Thank you! I now know what "<<subject<<" is."<<endl;
              cout<<endl;
              cout<<"How about another question!"<<endl;
              keepgoing = 1;
              }
              else {
              cout<<endl;
              c_file>> response;
              cout<<response<<endl;
              cout<<endl;
              cout<<"There you go! Thats all I know about "<<subject<<"!"<<endl;
              cout<<endl;
              cout<<"So let's get on to the next question..."<<endl;
              keepgoing = 1;
              }
              }
        else if ( question == "who are you?" ) {
        cout<<"I am Smarterthanchild, the world's only completely"<<endl;
        cout<<"useless talking robot and hopefully there are many"<<endl;
        cout<<"in development"<<endl;
        cout<<endl;

        }
        else {

        cout<<endl;
        cout<<"Ask me another question and we'll see if I can understand!"<<endl;
        keepgoing = 1;
        }
} while ( keepgoing == 1 );

I ave a problem where it will only read the first word from the file.

---

Code:

---

#include <iostream>
#include <fstream> //ifstream, ofstream
#include <string>

using namespace std;


int main()
{
        //write to file:
        string data = "a loose fitting t-shirt";
        ofstream outFile("C:\\TestData\\data.txt");
        outFile<<data;

        outFile.close();

        //read from file:
        ifstream inFile("C:\\TestData\\data.txt");
        if(!inFile)
        {
                cout<<"couldn't open file"<<endl;
                return 1;
        }
       
        string input;
        getline(inFile, input);

        cout<<input<<endl;

        return 0;
}

---

So rather than using (example) x_file>>string I would use getline.

The >> operator is programmed to skip leading whitespace(spaces, tabs, newlines) and stop reading when it encounters whitespace.

getline() stops reading when it encounters a '\n' character. If you manually enter data into a file, when you hit return either an invisible \r\n(windows), \r(mac), or \n(unix) is entered at the end of the line. When you read from a file, C++ automatically converts the various line termination characters to a '\n', so getline() will stop when it reads the '\n'.

On the other hand, if you programatically enter data into a file, you have to enter a '\n' with your program when you want the line to terminate, e.g.:

outFile<<myString<<'\n';

This formatting..is horrible.. put a { on its own line every time and a tab on the next, put the } on the last line by itself without the tab

I am sorry....I'm not exactly an expert yet anyway.

What are you using to write your code? Most compilers have editors that automatically indent the next line after you type a '{'. So, you just type a '{' character and hit return, and your code is indented. Then when you type the closing '}', and hit return, the editor automatically slides it over to the left to match the first brace. So you end up with something like:

---

Code:

---

if(!inFile)
{
        cout<<"couldn't open file"<<endl;
        return 1;
}
