Just a tip - you might want to store your filename somewhere in memory after typing it in, so that you can actually do stuff with it. Your fp pointer is a filehandle for your log file, which you'll mostly be wanting to write to, not read from. I'm guessing that you have a data file of sorts with the necessary info which is what you'll be fscanf()ing in. It's unlikely you'll be reading data from a file handle which has been opened for writing!
