First attempt Load/save program

[Password Protection]

Yesterday I was looking through tutorials, and nothing really made much sense to me. The first parts made sense, but then it seemed like a huge technological jump took place in the writing. So, I took a stab in the dark yesterday - and it doesn't work as I want it to. It compiles with no errors, just doesn't give the correct numbers... at all.

I left out the int main and #include statements.
So here's the basic script:

int wood = 5;
ofstream fout("save.txt");
ifstream fin("save.txt");
fin >> wood;
cout << "Your current wood: " << wood;
wood = 6; //NOTE! This actually changes in the game. Just makes it easier to see if it saves.
fout << wood;
fout << flush;
fout.close();
system("Pause");

Why you open SAME file in different streams before closing even 1?

For example:
First open file for reading data.
Read the data from the file.
Close the file.

Now it would be time to modify data...

Now open a file (=stream) again but this time for "printing" data to the file.
Insert the data to the file.
Close the output file

I have no idea...

So should it be done like this?

int wood = 5;
ifstream fin("save.txt");
fin >> wood;
fin.close();
cout << "Your current wood: " << wood;
wood = 6; //NOTE! This actually changes in the game. Just makes it easier to see if it saves.
ofstream fout("save.txt");
fout << wood;
fout << flush;
fout.close();
system("Pause");

EDIT: I tested it just now, and it seems like it's working great! Thanks for the help.
