Virtual Functions

    This problem is driving me crazy! My code works for the first test case but fails on about half of them. I downloaded the textfiles for the input and output of one of the cases it fails on. Then I used the file as an input and piped the output to another file. I used a diff tool to see if there was any difference between the expected output and the generated output and there was none. If anyone can let me know what I am doing wrong I would greatly appreciate it.

    static int student_id, professor_id;
class Person
{
    public:

    int age;
    string name;

    // = 0 indicates pure virtual function, must be overridden
    virtual void getdata() = 0;

    // virtual function with definition, does not have to be overridden
    virtual void putdata() = 0;
};

class Professor : public Person
{
    public:
    int publications;
    int id;

    Professor()
    {
        ++professor_id;
    }

    void getdata()
    {
        cin >> name >> age >> publications;
        id = professor_id;
    }

    void putdata()
    {
        cout << name << " " << age << " " << publications << " " << id << endl;
    }
};



class Student : public Person
{
    public:
    int marks[6];
    int marks_sum;
    int id;

    Student()
    {
       ++student_id;
    }

    void getdata()
    {
        cin >> name >> age;
        id = student_id;
        for(int i = 0; i < 6; i++)
        {
            cin >> marks[i];
            marks_sum += marks[i];
        }
    }

    void putdata()
    {
        cout << name << " " << age << " " << marks_sum << " " << id << endl;
    }
};
