simple question

Post by dsjoka » Thu Feb 10, 2011 1:38 pm


I have maybe 1 day of scheme/lisp experience, and glad I found this forum.

I have a simple question.

Ok I know theres a null for detecting an empty list. However I have no idea how to find how many elements in a list. ie: (a) would return 1. Is there like a count function?

This function is called "length" in both Common Lisp and Scheme.
