How do you write multiple lines in a .txt with recursion?

help you fix your problem Im a programming student and the Engineer told us to write an algorithm using recursion for the math problem "Hanoi Towers". That is done, Im able to print the instructions on the console, but I need to write the instructions on a .txt file. I have managed to create the file and write the first line of text on it, but the rest doesn't really appear. I really need some help with this guys. , Open the fstream object from main to make things easy:

void torresdehanoi(int disco, int torre1, int torre2, int torre3, ofstream& myFile) {

    if (disco == 1) {
        myFile << "Mover disco de Torre " << torre1 << " a la torre " << torre3 << endl;
    }
    else {
        torresdehanoi(disco - 1, torre1, torre3, torre2, myFile);
        myFile << "Mover disco de Torre " << torre1 << " a la torre " << torre3 << endl;
        torresdehanoi(disco - 1, torre2, torre1, torre3, myFile);
    }
}

int main()
{
    ofstream myFile;

    int disco = 0, torre1 = 1, torre2 = 2, torre3 = 3;

    cout << "Con cuanteas piezas desea calcular el algoritmo?" << endl;
    cin >> disco;

    myFile.open("SolucionTorresDeHanoi.txt");
    if (myFile.is_open()) {
        torresdehanoi(disco, torre1, torre2, torre3, myFile);
        myFile.close();
    }
    return 0;
}

How to write multiple lines in a file when this multiple lines take as a input from a JTextarea?

I think the issue was by ths following , I take multiple lines as a input from a JTextarea, If I write it in a file, then I get that the multiple lines are write in a one line in file , Slighty better version would be :

    try {
        PrintWriter fstream = new PrintWriter(new FileWriter("log.txt"));
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }


 for(String word : jTextAreaName.getText().split("\n"))  {    
    fstream.println(word); 
} 
     fstream.flush();

Any of those help Start your command with $', end it with ' and use \n\ for newlines, like this:

RUN echo $'[repo] \n\
name            = YUM Repository \n\
baseurl         = https://example.com/packages/ \n\
enabled         = 1 \n\
gpgcheck        = 0' > /etc/yum.repos.d/Repo.repoxyz

I wish this helpful for you One of the properties of stdio streams, especially when connected to files, is that they buffer input and output and then write it in large pieces. Thus, unless you've interfered with the buffering of fp, you automatically get I/O behavior similar to approach 2 from approach 1.
Furthermore, you can control the size of the buffer via setvbuf(), so if you want a 10000-byte buffer then you can ensure that, allowing an approach 1 solution with I/O semantics even more similar to your approach 2. Unless you want the concatenated string for more than just printing it, there's pretty much no reason to prefer approach 2 when approach 1 is feasible.
