Consider the Base and BaseBall classes defined below. There are two things wrong with this code, both having something do do with the output function$($s$).$ What are the problems, and how can they be fixed?

class Base $\{$

public:

virtual void output$()$;

Base$()$ : x$("$home$"),$ y$("$plate$"),$ pop$(42)\{\}$

private:

string x$,$ y;

int pop;

$\}$;

class BaseBall: public Base $\{$

public:

void output$()\{$

cout $<<"$at $"<<$ x $<<""<<$ y $<<","$;

cout $<<"$ the batter hit the ball $"<<$ pop $<<""<<$ fly $<<$ endl;

$\}$

BaseBall$()$ : fly$("$feet$"),$ Base$()\{\}$

private:

string fly;

$\}$;
