Question

how to create a list in LISP and accepting elements of list from user?

Answer 1

Use the read function to read user input. For example:

[6]> (list (read) (read))
joe
moe
(JOE MOE)

joe and moe are my input lines, terminated by a newline (pressing Enter). The list function creates a new list.

Answer 2

If you want to read the elements of a list of unknown length, you could do it like this (takes input until NIL) [CL]:

(loop for read = (read)
      while read collect read)

Alternatively, the easiest possibility actually is:

(read)

Because the user may enter (foo bar baz 1 2 3) here, too.
