c++ - Passing a vector<class> myvector to an constructor and accessing it -

sorry if question similar posted already, don't know how word question properly. how can access "william" , "shakespeare" cout << passed author object shakespeare, passed vector of authors passed book object play?

class author{} //has private variables first_name , last_name , getter                 //functions in public.  class book{ private:     vector<author> author_mem; public:     book(const vector<author>& author_fn):author_mem(author_fn){}     vector<author> get_author_list() const {return author_mem;} }  int main(){     const author shakespeare("william","shakespeare");     const vector<author> authors = {shakespeare};     const book play(authors);     //initiial idea have      //cout << play.get_author_list.at(0)  } 

i don't know how named accessors author class, let's it's getfirstname , getlastname.

that should work:

cout << play.get_author_list().at(0).getfirstname(); cout << play.get_author_list().at(0).getlastname();
