Perform the weekly set up instructions for project 3, homework c.
A file answers.txt with answers to the following questions.
data3
function defines an equality
test in a funny way: (<- (= ?x ?x))
.
Is that a typo? Should not the second "?x" be different to the first?
And should there be a body to the rule?
A revised version of 15.lisp
that supports and the code
in the younger
predicate of data3
:
(do (print ?x))
replaces
"?x" with its current binding and prints it.
(say str args)
is defined in ‘3/c/tricks.lisp’
and I want to be able to call say
very simply from within my rules. For an
example of that call, see the younger
predicate of data3
.
Note that if all the above works, then the !three
deftest
should now work.
