C++ Program crashing from print function -

-

at moment program crashing after displaying 1 line out of 250 supposed display. here code:

string movielist::printall() {    (int = 0; < last_movie_index; i++) {         movies[last_movie_index].movie::printmovie();    } }  string movie::printmovie() {     cout << fixed << setprecision(1) << rating << "\t\t" << votes << "\t\t" << "(" <<             year_made << ")" << "\t" << name << endl; }

full movie , movielist class:

class movie { public:     movie();     movie(string n, int y, int v, double r);     string get_name();     void set_name(string n);     int get_year();     void set_year(int y);     int get_votes();     void set_votes(int v);     double get_rating();     void set_rating(double r);     string printmovie();  private:     string name;     int year_made;     int votes;     double rating;  };  movie::movie() {     name = "null";     year_made = 0;     votes = 0;     rating = 0.0; }  movie::movie(string n, int y, int v, double r) {     name = n;     year_made = y;     votes = v;     rating = r; }  string movie::get_name() {     return name; }  void movie::set_name(string n) {     name = n; }  int movie::get_year() {     return year_made; }  void movie::set_year(int y) {     year_made = y; }  int movie::get_votes() {     return votes; }  void movie::set_votes(int v) {     votes = v; }  double movie::get_rating() {     return rating; }  void movie::set_rating(double r) {     rating = r; }  string movie::printmovie() {     cout << fixed << setprecision(1) << rating << "\t\t" << votes << "\t\t" << "(" <<             year_made << ")" << "\t" << name << endl; }  class movielist { public:     movielist(int size);     ~movielist();     int length();     bool isfull();     void add(movie const& m);     string printall();  private:     movie* movies;     int last_movie_index;     int movies_size;     int movie_count = 0;  };  movielist::movielist(int size) {     movies_size = size;     movies = new movie[movies_size];     last_movie_index = -1; }  movielist::~movielist() {     delete [] movies; }  int movielist::length() {     return last_movie_index; }  bool movielist::isfull() {     return last_movie_index == movies_size; }  void movielist::add(movie const& m) {     if (isfull()) {         cout << "cannot add movie, list full" << endl;         return;     }     last_movie_index++;     movies[last_movie_index] = m; }  string movielist::printall() {    (int = 0; < last_movie_index; i++) {         movies[i].movie::printmovie();    } }

my array movies dynamically allocated (i.e movies = new movie[movies_size];). noticed using cout << movies[1] << endl not work in printall function. why crashing possibly? , can fix it?

this won't solve problem, if want make cout << movies[i] << endl work, need define following function in movie class:

friend ostream& operator<<(ostream& ostr, const movie& movie){     ostr << fixed << setprecision(1) << rating << "\t\t" << votes << "\t\t" << "(" <<             year_made << ")" << "\t" << name ; }
