How do I write a code on

using the player, Junior Player and Senior Player class declarations below attempt the question
class Player
{
    string name;
    string PlayerId;
public:
    Player();
    Player(string, string);
    void Register(string, string);
    void Display();
    void GivePoint();
};
class JuniorPlayer :public Player
{
    int bonusAmount;
public:
    void Display();
    JuniorPlayer incrementBonus();
}
a.once the player class is abstract what single change you must do in junior Player class to make it non abstract
b.write a constructor that would Call from Junior Player class the player class parameterized constructor and also give values to Junior Player class data members and player class data members
