Borland C++ Saving things to txt files

Jayfrin · 04-14-2008, 08:05 AM

I'm using Borland C++ on windows and I was wondering how I could save things, I have composed code to save one thing to a txt file but everytime I try to add another thing it just overwrites, I was wondering how I could use vectors to save multiple things to a text file then have the program load them all.

This is the composition so far:

Code:

{
        cout <<"your current age is"<< endl;
        ifstream in("Agesave.txt");
        in >> currentage;
        in.close();
        cout <<"****"<< currentage <<"****"<< endl;
        cout <<"Enter your age"<< endl;
        cin >> age;
        ofstream save("Agesave.txt");
        save << age;
        save.close();
        return 0;
}

This is excluding the preprocessors and variable declarations, it works fine and saves and loads 1 number how can I make it load multiple numbers.

Any help would be nice, thanks,
Cheers

I don’t understand the question. Is it simply that you want to open your output stream in “append” mode instead of truncating?

I'm sorry, I am bad with words, but what that code does is it saves the imputed number into the .txt file (say number 20) then ends. Then once the program is run again if I save another number to the same .txt file (30), the previously entered number(20) gets replaced with the new one (30), and only one number will stay there. Does that makes more sense?

I do know it is a language problem maybe the "save"

Yes the append was the problem.

So you can open your ofstream like this instead:

Code:

std::ofstream save("Agesave.txt", ios_base::out | ios_base::app);

to get “append” output mode.
