For questions $5-9,$ consider the following two classes, Player and BasketballPlayer:

class Player

$\{$

$$ protected:

$$string name;

$$double weight;

$$double height;

$$ public:

$$Player$($string n$,$ double w$,$ double h$)$

$\{$ name $=$ n; weight $=$ w; height $=$ h; $\}$

$$string getName$()$ const

$\{$ return name; $\}$

$$virtual void printStats$()$ const $=0$;

$\}$;

class BasketballPlayer : public Player

$\{$

$$ private:

$$int fieldgoals;

$$int attempts;

$$ public:

$$BasketballPlayer$($string n$,$ double w$,$

$$ double h$,$ int fg$,$ int a$)$ : Player$($n$,$ w$,$ h$)$

$\{$ fieldgoals $=$ fg; attempts $=$ a; $\}$

$$void printStats$()$ const

$\{$ cout $<<$ name $<<$ endl;$$

$$cout $<<$ "Weight: $"<<$ weight;$$

$$cout $<<"$ Height: $"<<$ height $<<$ endl;

$$cout $<<"$FG: $"<<$ fieldgoals;

$$cout $<<"$ attempts: $"<<$ attempts;

$$cout $<<"$ Pct: $"<<($double$)$ fieldgoals $/$ attempts $<<$ endl; $\}$

$\}$;

int main$()$

$\{$

$$ Player$*$ ptr;

BasketballPlayer johnson$("$Magic Johnson", $100,200,300,400)$;

$$

ptr $=$ &johnson;

$$ ptr$->$printStats$()$;

$$

$$ return $0$;

$\}$

$5.$ What does $=0$ after function printStats$()$ do$?$

$6.$ Would the following line in main$()$ compile: Player p; $--$ why or why not?

$7.$ Could I remove the printStats$()$ member function from BasketballPlayer?$$ Why or why not?

$8.$ Would the following line in main$()$ compile: Player $*$ptr; $--$ why or why not?

$9.$ Write code which creates a Player pointer $($e$.$g$.$ Player $*$p$),$ creates an object of class BasketballPlayer, and assigns the address of the object to the pointer.$$ Why does this work?
