    write to .txt file in columns

    How could I write to a text file so that it appears in column format? This is for a .log file.

    It should look something like this:

    Code:
    <date>		<address>	<file>
    021125		11.34.56.156	/thisdir/thisfile
    021126		5.12.15.12	/thatdir/thatfile
    ....
    Is there a function for this or do I need to write one?

    Thanks in advance,

    Seron

    Yes there is a function: fprintf (read the - (negative) flag)

    I think you can do something like that:

    fprintf(fp,"%s\t%d\t%d\n",nm,level,points);
    This is an example

    I think, this should work.

    A tab doesn't always work.

    What about a normal fprintf with - (negative flag)?

    Code:
    printf("[%-20s] [%-20s] [%-20s]\n", "aaa", "aaaaaa", "a");
    printf("[%-20s] [%-20s] [%-20s]\n", "bbbbbbbbbb", "b", "bbbbb");
    Output:
    Code:
    [aaa                 ] [aaaaaa              ] [a                   ]
    [bbbbbbbbbb          ] [b                   ] [bbbbb               ]
