Hello I have tried lots of things to my publisher code but i cant seem to get it to store the string that's being sent to it please help me fix it. I looked at the median variables and it just seems to me the those variables are not sending the data to the class members.

class BookType
{
private:

    string publisher;
    string authors[4];
    int tracka;
    int copy;
    int Booktracker;

public:
    BookType()
    {

    }
    void setpub(const std::string &pr)
    {
         publisher = pr;
    }
    string getpub()
    {
        return publisher;
    }
    void setnumAuthor(int a)
    {
        tracka = a;
    }
    void setauthor(const std::string &a, int tracka)
    {
        for (int tracka; tracka<4; tracka++)
        {
            authors[tracka] = a;
        }
    }
    void setTBook(int T)
    {
        Booktracker = T;
    }
    string getauthor()
    {
        for (int i = 0; i < 4; i++)
        {
            return authors[i];
        }
    }
};

int main()
{



    optionmenu();


    system("pause");
        return 0;
}

void optionmenu()
{
    BookType Book[10];

    string author;
    char choice;
    string pub;


        cout << "please enter the author(s) name(s), if less then 4 authors leave (NA) in the leftover blanks." << endl;
        for (int ai = 0;  ai < 4; ai++)
        {
        getline(cin, author);   
        Book[i].setnumAuthor(ai);
        }


        cout << "what is the publisher of the book?" << endl;
        getline(cin, nu);
        getline(cin, pub);

        Book[i].setpub(pub);
