c++ - What happens inside when we write to a file without opening it?

for example if i write to a file which is not there where my << given string to write goes?

int main(int argc, char** argv) {
    fstream my_file;

    if (argc>1)
    {
            my_file.open("my_file.txt", ios::out);
            cout << "File1 created successfully!"<<endl;
    }


    my_file << "Guru99";
    my_file.close();
    cout<<"Done"<<endl;

    return 0; }

Will it put it in memory or put it in dev/null kind of area?
