Reading and Writing Files

[James Hagonoy]

Hi,I have a Question about reading and writing a file

im little bit curious about this.

for example I write and save it to a notepad "Helo world"
then I want it to do in reverse order then in turn in to dlrow oleH

and it will produce another notepad.

Files always read in a forward direction. To reverse a file you would read the entire file into a buffer and process the buffer from the end to the beginning.

If the file is oo large for meory, you can read records from the beginning to the end placing each record in a linked list. You then reverse the file by processing the list backwards and the data in each node backwards.

Bon appetit!
