C++ MovieList array and pointer -

i'm still bit stuck on part on assignment.

here prompt asking:

now can modify loadmovies function create movielist object , add each of movie objects it. function loadmovies should return pointer movielist object. means need create movielist object dynamically , on heap.

change main function , store returned movielist pointer in variable. test if works expected, can use printall function of movielist object.

here code far:

class movielist {  public:     movie* movies;     int last_movie_index;     int movies_size;     int movie_count = 0;  movielist(int size) {     movies_size = size;     movies = new movie[movies_size];     last_movie_index = -1; }  ~movielist() {     delete [] movies; }  int length() {     return movie_count; }  bool isfull() {     return movie_count == movies_size; }  void add(movie const& m) {     if (isfull())     {         cout << "cannot add movie, list full" << endl;         return;     }      ++last_movie_index;     movies[last_movie_index] = m; }  void printall() {     (int = 0; < movie_count; i++) {         movies[last_movie_index].printmovie();     } }  };  void readmoviefile(vector<string> &movies); void loadmovies();  enum moviesortorder {     by_year = 0,     by_name = 1,     by_votes = 2 };  int main() {     loadmovies();      // todo:     // need implement movie , movielist classes ,     // methods below program produce     // output described in assignment.     //     // once have implemented everything, should able     // uncomment code below , run program.      movielist *movies = loadmovies();      //    // test methods movie , movielist classes         //printallmoviesmadeinyear(movies, 1984);         //printallmovieswithstartletter(movies, 'b');         //printalltopnmovies(movies, 5);          //delete movies;     return 0; }  void loadmovies() {     vector<string> movies;     readmoviefile(movies);      string name;     int year;     double rating;     int votes;      (int = 0; < movies.size(); i++)     {         istringstream input_string(movies[i]);         getline(input_string, name, '\t');         input_string >> year >> rating >> votes;         movie movie (name, year, votes, rating);         movie.printmovie();     } } 

now i'm stuck @ professor asks me modify loadmovies in prompt , turn pointer. i'm drawing blanks. reason if try compile says:

c:\users\andy\documents\c++ homework\moviestatisticsprogram\moviestatsprogram.cpp:163: error: void value not ignored ought      movielist *movies = loadmovies();                                     ^ 

the order of constructor wrong

movielist(int size) {     movies = new int[movies_size];  // movies_size hasn't been initialized yet!     movies_size = size;     last_movie_index = -1; } 

it should be

movielist(int size) :  movies_size{size}, movies{new int[size]}, last_movie_index{0} {} 

though @scottmcp-mvp noted array should be

movie* movie; 

so constuctor be

movielist(int size) :  movies_size{size}, movies{new movie[size]}, last_movie_index{0} {} 

some advice getting started on remaining functions

length function return how many current used last_movie_index.

isfull check if last_movie_index == movies_size - 1

add need use last_movie_index figure out element in array store movie.

printall have iterate [0] [movie_count] , print out each element.

your add function like

void movielist::add(movie const& m) {     if (isfull())     {         std::cout << "cannot add movie, list full" << std::endl;         return;     }      movies[last_movie_index] = m;   // assigns copy array     ++last_movie_index;             // increment movie index }
