Homework Help

[cloud125]

Hello, I was working on my C++ homework and was wondering if anyone could help me with part of it. I wrote the .cpp and .h files but now I am stuck. Here is what I am supposed to do:

1. Write a subprogram (not a method) void promptForMovie(Movie & myMovie); that prompts the user for movie information, and returns a Movie object to the calling program. When this command is executed, the user will be asked to supply the attributes for the movie.
2. Write a method void output(ostream & out); that will display movie information as follows:
Movie:
Director:
Year:
Rating:
IMDB URL:

Here is my header file: MovieClass.h

// This is the header file that includes the interface of the Movie class

#ifndef _MOVIE_
#define _MOVIE_

#include <string>

using namespace std;


	enum Movie_Rating {G,PG,PG13,R,NC17,NR} ;


	class Movie
	{


	  public: // interface of the Socialite_user class
		  	
		//------------ Constructors ------------------
			
			Movie();
			Movie(const string& title) ;
			Movie(const string& title, 
			      const string& director, 
			      Movie_Rating rating,
			      unsigned int year,
			      const string& path) ;
		  	
		// ------------------------------------------------------
		// ----- Destructor -------------------------------------
		// ------------------------------------------------------
		
		//	~Movie();  // To be implemented in a future assignment.
	  	
		//------------ Inspectors --------------------
	  	
			string getTitle() const ;
			string getDirector() const ;
			Movie_Rating getRating() const ;
			unsigned int getYear() const ;
			string getURL() const ;
	  	
		//------------ Mutators ---------------------

			void setTitle(const string& title); 
			void setDirector(const string& director) ;
			void setRating(Movie_Rating rating)  ;
			void setYear(unsigned int year)  ;
			void setURL(const string& path)  ;


		private: // private data fields associated with Socialite_user objects
			// Underscores indicate a private member variable

			string title_ ;
			string director_ ;
			Movie_Rating rating_ ;
			unsigned int year_ ;
			string  url_ ;
		
	};

#endif 

MovieClass.cpp :

// This is the file that includes the implementation of the Movie class

#include "MovieClass.h"
#include <string>
#include <cstdlib>
#include <ciso646>
#include <sstream>

using namespace std;


//-----------Constructors-----------------

Movie::Movie()
{
		title_ = "";
		director_ = "";
		url_ = "";
		rating_;
		year_;

}

Movie::Movie(const string& title)
{
	title_ = "";
}

Movie::Movie(const string& title, const string& director, Movie_Rating rating, unsigned int year, const string& path) 
{
		title_ = "";
		director_ = "";
		url_ = "";
		rating_;
		year_;
}


//---------------Inspectors--------------------------

string Movie::getTitle() const
{
	return title_;
}

string Movie::getDirector() const
{ 
	return director_;
}

Movie_Rating Movie::getRating() const
{
	return rating_;
}

unsigned int Movie::getYear() const
{
	return year_;
}

string Movie::getURL() const
{
	return url_;
}

//--------------------Mutators-------------------

void Movie::setDirector(const string& director)
{
	director_ = director;
}

void Movie::setRating(Movie_Rating rating)
{
	rating_ = rating;
}

void Movie::setYear(unsigned int year)
{
	year_ = year;
}

void Movie::setURL(const string& path)
{
	url_ = path;
}

And this is supposed to be my test file; I am pretty sure I wrote this completely wrong. I think this is where I would put the subprogram and method they are asking for?: main.cpp

// This is the file that will test the implementation of the MovieClass

#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>
#include "MovieClass.h"

using namespace std;



//------------------------------------------------------
//	Prints out Movie Information
//------------------------------------------------------

	void output(ostream & out);

int main(void) 
{
	Movie promptForMovie;

	cout << "Movie: " << Movie.setTitle << endl;
	cout << "Director: " << Movie.setDirector << endl;
	cout << "Year: " << Movie.setYear << endl;
	cout << "Rating: " << Movie.setRating << endl;
	cout << "IMDB URL: " << Movie.setURL << endl;
	
	ofstream myfile;
    myfile.open ("MovieTest.txt");

    myfile << "Movie: ";
    myfile << promptForMovie.getTitle();
    myfile << "\n";
	myfile << "Director: ";
	myfile << promptForMovie.getDirector();
	myfile << "\n";
	myfile << "Year: ";
	myfile << promptForMovie.getYear();
	myfile << "\n";
	myfile << "Rating: ";
	myfile << promptForMovie.getRating();
	myfile << "\n";
	myfile << "IMDB Url: ";
	myfile << promptForMovie.getURL();
	myfile << "\n";

    myfile.close();
    return 0;
}

Thank you

First error that i can see is:

cout << "Movie: " << Movie.setTitle << endl;
	cout << "Director: " << Movie.setDirector << endl;
	cout << "Year: " << Movie.setYear << endl;
	cout << "Rating: " << Movie.setRating << endl;
	cout << "IMDB URL: " << Movie.setURL << endl;

the bracket are missing and i suppose you wanted to call the getTitle, getDirector ecc... Or you should call the setters with the cin operator...

Yea I'm pretty sure that whole section is wrong. I want to prompt the user for this information and then call it so I can output the information. How would I write a subprogram that would do that?

[LaboPie]

So for the console prompt part it should be:

cout << "Movie: " << promptForMovie.getTitle() << endl;
	cout << "Director: " << promptForMovie.getDirector() << endl;
	cout << "Year: " << promptForMovie.getYear() << endl;
	cout << "Rating: " << promptForMovie.getRating() << endl;
	cout << "IMDB URL: " << promptForMovie.getURL() << endl;

in this way your program will write in the console that attibutes, but you need to insert some values. So before that you should write:

cout << " Insert Movie: " << endl;
string tempString; 
cin >> tempString;
promptForMovie.setTitle(tempString);

and so on for all the data you wanna insert.

Thanks! Now how would I write a method void output(ostream & out); that will display movie information?
