Question

Hey i was working on this little method i guess you call them messing around trying to get my grip on swi-prolog before I have my big project assigned in a week or so at university. Its pretty obvious what it does say i say “colors(yellow,F). it will give me banana, lemon and so on…

colors(C,F):-fruits(F,C)

Now my question is i know i can use list_to_set(F, (something else)), to make the output into one list instead of having to hit ‘;’ to get all of the fruits. THOUGH… is there anyway i can incorporate the list making into the actual method?

cheers!

Answer 1

Okay found out how to:

colors(C,F):-findall(C,fruits(F,C),C).

simple enough, just had to stick it in there. Thanks Anyways!
