Description
Prolog seems to be ignoring the second
checkForPeriods
Solution
Prolog tries the predicates in the order they're listed! Since the first predicate is still valid when C is 0, it gets used and C goes into the negatives. To solve this I just needed to reorder the two.
Comment
This caused me so many headaches. I was trying to do
this, but it kept going negative until it ran out of stack. As you can probably tell, I have no background in Prolog. I'm learning it while I use it to complete this program.
