    File Length

    How do you determine the length of a file without manually traversing it from the beginning and looking for eof?

    file.seekg ( 0, ios::end );
    int size = file.tellg();

    My best code is written with the delete key.

    or if you are using handles, you can use filelength (), and if you need a translation from streams you can do filelength ( fileno (stream));

    If you are using Preulde's method you need to besure to open the file in binary mode or else the new line characters and other things can mess up the size.
