Write vector to text file?

[toasterstoast1]

I have a class Film of which i have created a vector of the data
i now want to save this data of class Film to a text file

I have been searching online everywhere and do not know how to do it

int main(){
	
	string name, director, year, language;
	vector<Film> f;

	ofstream newFile;
	newFile.open("film.txt");

	int i;
	for (i=0;i<2;i++){
	Film a;
	f.push_back(a);
	}
	

	for (int i=0; i<2; i++)
	{
	newFile << f[i] << '\n';
	}

	newFile.close();

	system ("pause");
	return 0;

}

Film::Film(){
	cin.ignore();
	
	cout << "FILM DETAILS: " << '\n' << '\n'; 
	cout << "Enter name: "; getline(cin, name);
	cout << "Enter director: "; getline(cin,director);
	cout << "Enter year: "; getline(cin,year);
	cout << "Enter language: "; getline(cin,language); cout <<'\n';

Something along these lines, perhaps:

#include <iostream>
#include <string>
#include <vector>
#include <fstream>

struct film
{
    std::string name ;
    std::string director ;
    std::string year ;
    std::string language ;
};

// write to an output stream
std::ostream& operator<< ( std::ostream& stm, const film& f )
{
    // write one string per line, end with a blank line
    return stm << f.name << '\n' << f.director << '\n' << f.year << '\n' << f.language << "\n\n" ;
}

// read from an input stream
std::istream& operator>> ( std::istream& stm, film& f )
{
    // read one line per string, ignore blank lines at the beginning

    // read the first line, after skipping over blank lines
    while( std::getline( stm, f.name ) && f.name.empty() ) ;

    // read the remaining lines
    if( std::getline( stm, f.director ) && std::getline( stm, f.year ) && std::getline( stm, f.language ) ) ; // do nothing more
    else f = {} ; // clear all fields in f

    return stm ;
}

int main()
{
    const std::string file_name = "films.txt" ;

    {
        const std::vector<film> favourites = { { "Au hasard Balthazar", "Bresson", "1966", "French" },
                                               { "Stalker", "Tarkovsky", "1979", "Russian" },
                                               { "Smultronstället", "Bergman", "1957", "Swedish" },
                                               { "Ikiru", "Kurozawa", "1952", "Japanese" },
                                               { "Werckmeister harmóniák", "Bela Tarr", "2000", "Hungarian" },
                                             };

        std::ofstream file(file_name) ;
        for( const film& f : favourites ) file << f ;
    }

    {
        std::vector<film> film_list ;
        std::ifstream file(file_name) ;
        film f ;
        while( file >> f ) film_list.push_back(f) ;
        std::cout << film_list.size() << " items were read\n\n" ;

        for( const auto& f : film_list ) std::cout << f ;
    }
