//  Making FootballPlayer a derived class

/*
    To have FootballPlayer inherit from our Person class, the syntax is:
    After the class FootballPlayer declaration, we use a colon, the word
    “public”, and the name of the class we wish to inherit.

    This is called public inheritance.

        {}
        int getCaps() const { return m_caps; }
        int getGoals() const { return m_goals; }
};
/*
    When FootballPlayer inherits from Person, FootballPlayer acquires the
    member functions and variables from Person. Additionally, FootballPlayer
    defines two members of its own: m_caps and m_goals.

    This makes sense, since these properties are specific to a FootballPlayer
    , not to any Person.
