    Very Simple Data file question...

    I already have a list of stuff in my data.txt file.

    How do I add stuff to that data.txt file without erasing what's already in it?

    Thanks in advance

    You open the file with the ios::app mode.
    My best code is written with the delete key.

    ofstream outfile("data.txt", ofstream::ate);

    opens the file in append mode.

    Here is what I have tried...

    string newdata;

    ofstream fout ("data.txt", ios:app);

    fout << newdata;


    When I do this though, it erases everything that was already in it.

    I also tried the same only with ofstream::ate and it did the same thing. It erases everything and writes only newdata;

    could you post your code? There may be something else causing this.
