Saving Data

[Laelaps]

Hi, I am a novice and was wondering how I could save data, like a string or integer, to the hard drive to be accessed somehow later on, instead of everything being killed at the end of the program.
Thanks in advance for any help!

By writing them to a file:

Look up "serialization" as well.

Thank you!

Hey, how would I go about writing a user's input to a file?

  string mystring;
  getline (cin, mystring);

  ofstream myfile;
  myfile.open ("example.txt", ios::app);
  myfile << "Writing here.\n";
  myfile.close();

What would I change?

You'd just change it to myfile << mystring << endl;

I've tried that, and it doesn't seem to be working. Does it work for you?

using namespace std;
#include <iostream>
#include <string>
#include <fstream>

int main ()
{
    string mystring;
    cout << "What do you want to say? ";

        ofstream myfile;
        myfile.open ("conversaton.txt", ios::app);
        
        getline (cin, mystring);
        
        myfile << mystring << endl;
        myfile << "getline(cin, mystring)";
        myfile.close();

	
	return 0;
}

Oh wait, it is working for me; I was looking in the wrong folder. Sorry about that.
