List question

[Zoogy83]

Hello everyone,

quick question. I have a list made up and it can accept the users input. I was wondering if anyone could help me figure out how to add another 'sub item' to the list. I already have it set up for the user to input but need it to go to the same list. Also When I call back to the main menu of my program, and select show list nothing comes up. Any help would be great thanks.

Can you Show your Code here so anyone can help you.any way for inserting a item in list you simply can use list:ush_back method

Thanx

This is where the variables are declared




#include "Dvd.h"
#include "AddDelete.h"
#include "Type.h"
#include "Menu.h"


add::add()
// This is where the user inputs the movie title,
// and the main character. I may add a few more
// different things for the user to input.
{
cout << "\nYou have chosen to add a movie" << endl;
getline(cin, title);
cout << endl;
cout << "Movie title: ";
getline(cin, title);
cout << endl;
cout << "Is this correct for the title: " << title << "\n\n";
cout << "(Y, N): ";
cin >> confirm;

switch (confirm) // Gets the decision of the correct movie
{
case 'y':
case 'Y':
cout << "Thank You" << endl;
dvdArrayList:vdArrayList(title);
menu::menu();
break;
case 'n':
case 'N':
cout << "Try again" << endl;
add::add();
default:
cout << "Try again" << endl;
add::add();
}
}

void add::mainCharacter()
{
cout << "\n" << endl;
getline(cin, character);
cout << "Please enter a main character: ";
getline(cin, character);
cout << endl;
cout << "Is this correct for the main character: " << character << "\n\n";
cout << "(Y, N): ";
cin >> confirm;

switch (confirm) // gets the decision of the correct character
{
case 'y':
case 'Y':
cout << endl;
cout << "Thank You" << endl;
//dvdArrayList:vdArrayList(character);
break;
case 'n':
case 'N':
cout << endl;
cout << "Try again" << endl;
add::add();
default:
cout << "Please select again" << endl;
add::mainCharacter();
}

add::rating();
}

void add::rating()
// This is where the user selects the rating of his/her movie
{
cout << "Please select the rating by typing the coresponding number" << endl;
cout << endl;
cout << "1. G" << endl;
cout << "2. PG" << endl;
cout << "3. PG-13" << endl;
cout << "4. R" << endl;
cout << "5. Not Rated" << endl;
cout << "Rating: ";
cin >> ratings;

switch (ratings)
{
case '1':
cout << "You have chosen the rating: G" << endl;
type::type();
break;
case '2':
cout << "You have chosen the rating: PG" << endl;
type::type();
break;
case '3':
cout << "You have chosen the rating: PG-13" << endl;
case '4':
type::type();
break;
cout << "You have chosen the rating: R" << endl;
case '5':
type::type();
break;
cout << "You have chosen the raing: Not Rated" << endl;
default:
cout << "Invalid entry!" << endl;
cout << "Please choose again!" << endl;
add::rating();
}

}








This is where my list is





#include "Menu.H"
#include "Dvd.h"
dvdArrayList:vdArrayList()
{
}
dvdArrayList:vdArrayList(string title)
{
Movie.push_back (title);

list<string>::iterator iter;

for(iter = Movie.begin(); iter != Movie.end(); iter++)
cout << (title) << endl;
menu::menu();
}



The program runs, I just need to figure out how I could make the list accepth two more user inputs, character, and rating. The other problem is that it doesn't keep the input in the list.

First use Code tags .So anyone can Understand your Question.and Second Follow the given Link So you can feel Comfortable with list

Thank you for the site. I will look at it, and post if I have any more questions. How do you use code tags I am unsure.....

Code tags are easy to use....

How is the list in question declared? (the list where you want to add 2 more user inputs?)

Is it just std::list<std::string>? If that is the case, you might need to declare a struct or a class that holds whatever inputs related to one record, say:

//the datatypes are chosen by me, change them accordingly
struct MovieDetails
{
     std::string movie_name;
     std::string character;
     double rating;
};

And have the list as:

std::list<MovieDetails> movieDetailsList;

And proceed ahead, creating instances of movie details setting the attributes and pushing into the list. [You might be better off using std:eque/std::vector instead of std::list because I think you would be searching the container a lot for specific movies etc.]
