Animal Guessing binary tree game C++

[Kraken]

Hi, i have a bit of a problem here.

I have an assignment to do an animal guessing game using an original database and updating it as the user enters new animals in it. The program enters the file data into an array of structures, with the animal and question in the same variable(questi on) and the bool isAnimal tells me whether its an animal or a question. If its a question it is followed by two numbers; one for the position of the line to go to if the user enters "no" and another for "yes". The program works fine until the user inputs "no" for a new animal(updated animal) after he enters yes for a new question(that he entered the last time to differentiate between animals). Here is the code, and sorry if the variable names are bad. Im using windows xp and visual c++ 2005.

The experts on this site are more than happy to help you with your problems but they cannot do your assignment/program for you.

So you are aware of the rules please read the Posting Guidelines and particularly the Coursework Posting Guidlines.

sorry i did not mean for you to solve it for me, i just want to know why its not working.

By the way, x is the position of the next empty cell in the array of structures and c is the position of the line.

Thanks

No problem, someone can help you and point you in the right direction. You just need to be aware of our homework policy to make sure that you are not in violation.

And, I don't know if I edited down your code properly to the offending areas, but you may repost your code edited down to only the few lines that are actually causing the problem. This prevents others who are on a similar assignment from copying and using all of your code.

Yeah thanks, i think this part better represents my problem:

cout <<"Think of an animal and i will try to guess its name" << endl << endl;
 
    cout<< game[1].question <<"? [yes/no]" << endl;
 
    int c = 1;
    bool exit = false;
 
    while(!exit)
    {
 
        cin >> answer;
 
        if(answer == "yes")
        {
            if(game[game[c].yes].isAnimal == true)
            {
                cout<< "Is it a "<< game[game[c].yes].question << "? [yes/no]" << endl;
                cin >> answer1;
                exit = true;
            }
            else
                if(game[game[c].yes].isAnimal == false)
                {
                    cout << game[game[c].yes].question << "? [yes/no]" << endl;
                    c = game[c].yes;
                }
        }
        else
            if(answer == "no")
            {
                if(game[game[c].no].isAnimal == true)
                {
                    cout<< "Is it a "<< game[game[c].no].question << "? [yes/no]" << endl;
                    cin >> answer1;
                    exit = true;
                }
                else
                    if(game[game[c].no].isAnimal == false)
                    {
                        cout << game[game[c].no].question << "? [yes/no]" << endl;
                        c = game[c].no;
                    }
            }
    }
    cout << endl;
 
 
 
    if(answer1 == "yes")
        cout<<" I WIN!!!"<<endl << endl;
    else
        if(answer1 == "no")
        {
 
 
            cout << " I give up, what were you thinking of?" <<endl;
            cin  >> game[x].question;
            game[x].isAnimal = true;
 
            x++;
 
            game[x].question = game[game[c].no].question;
 
            cout<< "Please type a question that has a yes answer for "<< game[x - 1].question
                << endl << " and a no answer for " << game[game[c].no].question << " (without a question mark):" << endl;
 
            cin.ignore();
 
            getline(cin, game[game[c].no].question);
 
            game[game[c].no].isAnimal = false;
            game[game[c].no].no = x;
            game[game[c].no].yes = x - 1;
 
            x++;
 
        }

So now give us an example input and where the code breaks down.
