Which of the function declarations in this code are probably not const correct?

class Movie { public: Movie(const string& Title, const string& Director); Movie (const Movie&); string getTitle(); void getDirector () const; void setTitle(string aTitle); void setDirector (const string& aDirector) const; private: string theTitle; string theDirector; }; ostream& operator<< (ostream&, const Movie&); 

a		first constructor
b		copy constructor
c		getTitle
d		getDirector
e		setTitle
f		setDirector
g		theTitle
h		operator<<
