    Start by opening a file stream... then all will become clear to you
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Thumbs up

    Use this:
    ifstream OpenFile(char *filename, int open_mode);

    set the open_mode to ios::app
    which will append what to write to the end of the file.
