Sounds like you need to buy a C book or find a tutorial (try www.tutorgig.com). It'll take you forever asking about one statement at a time. There are numerous functions that will output to a file. fprintf() works just like printf() except that you add 'fp' as the first parameter: fprintf(fp, "%s\n", "some string); I believe putc() is the file version to output a single character. It's probably: putc(fp, 'c'); but I haven't used it in a while. You should be able to look it up as easily as I.
