OT: Look what I can do...

Suggestion for version 2:
Separate input, output and processing into their own functions. It's real good exercise. Something like

main(){
get_input( variables )
process_input( variables )
put_output(screen)
put_output(file)
}

My brother never learned to use functions, and now he codes his entire programs all in main().
So now he can't write big programs, because after a while it becomes too much to follow in one function.
Try reading a 500-line function! One page is plenty.

Nothing compared to my 500 or so lines of spagetti code written in qbasic.

Or my first serious program, which was almost a thousand lines of GW-Basic code.
All my variables were 4 or 5 character acronyms.
And it had no elses or block-ifs, since I didn't know about them at the time.
Instead, I used If-Dosomething-Goto

I'd estimate that up to 10% of the instructions in that program were gotos!

But at least it was neat, well organized spaghetti code.
