Here is my code:

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

int main()
{
    ofstream outFile;
    cout << "Writing rpgsave.txt." << endl;
    outFile.open("data\\rpgsave.txt");
    outFile << "10 3 0 10 3 0 10 3 0" << endl;
    outFile.close();
    cout << "Writing hasrun.txt" << endl;
    outFile.open("data\\hasrun.txt");
    outFile << "0" << endl;
    outFile.close();
    return 0;
}

It just won't seem to write up these two files (rpgsave.txt & hasrun.txt)... Thank's for reading this thread.

Probably because the directory data does not exist. The C++ iostream functions will not create a directory. You will need to use operating system specific functions, or maybe look into the boost filesystem library.

Oh that's the case. I thought it does create directories? Or does it only create files?

When you call open() the file will be created if does not exist or contents will be deleted unless you add 2nd argument to specify that you want to append.

Jim is of course correct..

No it doesn't create directories

Yes it only creates files.

Assuming your running Windows and by your indications you are...

This code example handles all eventualities and will write your .txt files to your project directory in a folder called 'data'.

#include <iostream>
#include <fstream>
#include <Windows.h>
using namespace std;

int main()
{
	ofstream outFile;
	cout << "Writing rpgsave.txt." << endl;
	outFile.open("data\\rpgsave.txt");
	if (outFile.fail() == false)
	{
		outFile << "10 3 0 10 3 0 10 3 0" << endl;
		outFile.close();
	}
	else
	{
		CreateDirectory("data\\", NULL);
		outFile.open("data\\rpgsave.txt");
		outFile << "10 3 0 10 3 0 10 3 0" << endl;
		outFile.close();
	}


	cout << "Writing hasrun.txt" << endl;
	outFile.open("data\\hasrun.txt");
	if (outFile.fail() == false)
	{
		outFile << "0" << endl;
		outFile.close();
	}
	else
	{
		CreateDirectory("data\\", NULL);
		outFile.open("data\\hasrun.txt");
		outFile << "0" << endl;
		outFile.close();
	}

	cout << "Press Return Key to Continue...." << endl;
	cin.ignore();
	cin.get();
	return 0;
}

Oh ok that's cool. There's a function that creates directories. Thank you everyone
