First off, great on you for rewriting an old assignment in a new 
language. That's one of the better ways I've found to learn new 
languages (and I learn new languages all the time) because it 
allows you to focus on the new language and how you might use 
that language rather than solving the problem at hand.

Second, this probably should be in D.learn (if I don't say it, 
someone else will). 
http://forum.dlang.org/group/digitalmars.D.learn if you're using 
the web interface.

Third, "exit(0)" is redundant in D. It'll exit with code 0 as 
long as execution terminates normally (i.e., no exceptions 
thrown).

Finally, what "doesn't work very well"? Without more information, 
I don't think anyone will be able to help you.

Take care.
