Bad memory allocation?

[Marnez]

When I run my program I get an error message: terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

How do I resolve this?

I'm trying to create a dynamically allocated array of structures and return it to the pointer created in main. I noticed that this error only occurs when trying to cout the members in main, as I am now where it crashes. If I try to cout (display) the members in the other function, it shows up perfectly.

#include <iostream>
#include <cstdlib>
#include <iomanip>
#include <string>
#include <fstream>

using namespace std;

struct Movie
{
    int year;
    string name;
    string director;
    int timesCalled;
};

Movie *readMovieInfo(int &size);

int main()
{
    int size;
    Movie *movieList;

    movieList = readMovieInfo(size);

    for (int i = 0; i < size; i++)
    {
        cout << movieList[i].year << "   ";
        cout << movieList[i].name << "   ";
        cout << movieList[i].director << endl;
    }

    return 0;
}


Movie *readMovieInfo(int &size)
{
    ifstream inFile;
    string file;
    Movie *movieList;
    movieList = new Movie[size];

    cout << "What is the name of the file you'd like to open? ";
    getline(cin, file);
    file.append(".txt");
    inFile.open(file.c_str());
    if(!inFile)
    {
        cout << "Can't open the input file!" << endl;
        exit(111);
    }

    inFile >> size;

    for (int i = 0; i < size; i++)
    {
        inFile >> movieList[i].year;

        getline(inFile, movieList[i].name, '\"');
		getline(inFile, movieList[i].name, '\"');
		movieList[i].name = movieList[i].name;

		getline(inFile, movieList[i].director, '\"');
		getline(inFile, movieList[i].director, '\"');
		movieList[i].director = movieList[i].director;
    }
    cout << "test";
    inFile.close();

/*
    for (int i = 0; i < size; i++)
    {
        cout << movieList[i].year << "   ";
        cout << movieList[i].name << "   ";
        cout << movieList[i].director << endl;
    }
*/
    return movieList;
}

The problem is that you have not assigned any value to size before you use it on line 42.

Oh my... Haha.. Thank you for pointing out such a bad mistake.
