C++ Derived classes

Sit and tinker with that derived classes and I have encountered some problems..

Here are the classes:

Code:

---

Class Person (

  public:

    Person (const string & n): name (n) ();

    const string & units () const;

    void andra_namn (const string & n);

    void skriv_info () const;

  private:

    string name;

  );



  class Course;



  class Student: public Person (

  public:

    Student (const string & n): Person (n) ();

    void borja_kurs (Course & k);

    void sluta_kurs (Course & k);

    void skriv_info () const;

  private:

    vector <Kurs *> courses;

  );



  class Course (

  public:

    Course (const string & name): knamn (name) ();

    const string & course name () (return knamn;)

    void ny_student (Student & s);

    void student_bort (Student & s);

    void exit ();

    void skriv_info () const;

  public:

    string knamn;

    vector <Student *> stud;
  );

---

And here are some features:

Code:

---

  const string & Privacy:: units () const

  (Return name;) 

  void Person:: skriv_info () const

  (Court << "Name:" <<name <<Endla;)

  void Student:: borja_kurs (Course & k)

  (

    for (int i = 0; i <kurser.size (); i + +)

      if (rates [i] == & k)

        return;

    kurser.push_back (& k);

    k.ny_student (* this);

  )

---

But how do you do then to call on these features inside the main?
Help appreciated!

Try this code,

Code:

---

int main ()
  (
    Personal sven ( "Sven");
    sven.skriv_info ();

    return 0;
  )

---

If you plan to use the polymorphism it gets a little trickier, but to say I can (or some other safe) try to explain.

Code:

---

string first name;
      string Lastname;
      Court << "Your first name:";
      cin>> first name;
      Court << "Your Surname:";
      cin>> last name;
      Person's name (first name + "" + last name);
      namn.skriv_info ();

---

Is this the easiest way for users to insert something into a class
or is there something better?

Thank you for taking the time.

Better / easier is a bit of a matter of taste and situation dependent. Want to change the name after you created the item? Then you need a set function. Otherwise, if it is not needed, or if you absolutely do not want it to change in circumstances, it is best to handle it in.

Code:

---

  string name;
          std:: Court << "Name:";
          std:: cin>> name;

          / / Alt 1:
          Person obj = Person (name);

          / / Alt 2:
          Person obj;
          obj.setName (name);
