Lisp simple question
문제
I have some not understanding actions from gnu clisp
Suppose, I have some code like (let ((x "Hi!"))(print x))
.
If I execute it from console (like, clisp fileName.lisp) I see
Hi!
But, when I execute it from interpreter, I see this text twice. Why?
Help me, please.
해결책
The interpreter always outputs the value of the last expression.
print
also returns the parameter as a value, "Hi!"
in your case.
That's why you see it twice.
(print "Hi!")
will give the same result.
