Does anyone know about LISP Programming

I am trying to make this program where I have 3 types of cars, which are ford bmw merc

ford has focus and fiesta BMW has 1series and 2series and the merc has SK100 and SK200

well basically i am trying to put them in the correct list for example focus will go into ford list and SK100 will go to the merc list.

the keyword here is sorted, so the cars r sorted to the correct list.

at the moment to store the data i will use defparameter

example

(defparameter *cars* ' ( focus fiesta 1series 2series SK100 SK200))

so now i want to create a funtion where the cars will go into the correct list. so fiesta will go and focus will go to the ford list.

so bascially I need to sort these cars out so they will be sorted to the correct list and to run it i will want to use defun

(test-a-car 2) the 2 means 2 cars a list so then it will display the cars in the correct list.

if u have any idea please help, cos i have no idea, so i would be so grateful if anyone could help

Re: Lisp

Even though this thread is approximately 10 months old, I'm going to resurrect it anyways.

What is the purpose of this? Normally I wouldn't ask, but what you're asking for here is for a list of cars to be provided, and reference it against an already existing library of cars - somewhat redundant, no?

(defparameter focus (cons "focus" "ford"))
(defparameter fiesta (cons "focus" "ford"))
(defparameter 1series (cons "1series" "BMW"))
(defparameter 2series (cons "2series" "BMW"))
(defparameter sk100 (cons "SK100" "Mercedes"))
(defparameter sk200 (cons "SK200" "Mercedes"))
(defparameter *cars* (list 'focus 'fiesta '1series '2series 'sk100 'sk200))
(defparameter *ford-cars* '())
(defparameter *merc-cars* '())
(defparameter *bmw-cars* '())

(defun test-a-car (car-to-test &optional cars-per-list)
  ;; NOTE: I've made the arguemtn to TEST-A-CAR optional, because it's useless
  ;; since the only way to do this is to reference the car in question to a pre-made
  ;; library, as I'm going to do, here.
  (cond ((equalp (cdr car-to-test) "ford") (push car-to-test *ford*))
            ((equalp (cdr car-to-test) "BMW") (push car-to-test *bmw*))
            ((equalp (cdr car-to-test) "Mercedes") (push car-to-test *merc*))))

(dolist (i *cars*)
  (test-a-car i))

Hi nick, good to see your enthusiasm. But please refrain from responding to threads that are clearly dead.

Why? It seems like a perfectly good question that someone who knows LISP can answer. It the resurrections that have no questions that are useless bumps.

No offense Mr Disney, but if you allow such a precedent to be set I could drag up all other posts that haven't been answered and answer them.

On the basis that it was aperfectly good question and I know the answer.

If nick wants to help with anyone learning lisp he can. There's a code snippet section, which looks empty , and also a tutorial section.

Mr. Thwee, the mods and Dani have had this discussion. It is OK to resurrect a thread with relevant information or question. Not being a mod, you would not have been privy to this information.

Keep in mind that the majority of people find DaniWeb through the search engines and land on specific threads. Therefore, while a thread might be a year old, thousands upon thousands of people might still be ending up at that thread daily via a google search, and it might still be helping all of them.

For this reason, I have no problem with members resurrecting dead threads so long as the reply is on topic and relevant. Remember, the thread helps a lot more people than just the thread starter.

If someone provides an alternative solution a year after the original thread starter's question has been solved, then great. That solution might help thousands of other people who ended up at the thread because they have the same problem as the thread starter.

Also keep this in mind - what is the difference between forums and live chat? In live chat, if someone posts a question, and someone else answers it, only that person got helped. The advantage to forums is that questions and answers live on to help others, and conversations can live on infinitely, with lots of people contributing to them over time. A thread is never really "dead" then if someone feels that they can contribute something additional to it. Posting time is irrelevant when everyone's posts live on forever here.
OK?

The official word:
You do realize that precedent could be open to abuse. I could in theory begin to answer say ten dead threads per day in all the forums I am active in for the next month. That's about 50 resurrected threads per day.

I bet you that will peeve off a lot of regular members. I'm not gonna do that of course. And I doubt anyone will.

Thanx for the secret info Mr Disney. :lol:

No, it won't, as long as you have something useful to contribute.
