Lisp Programming Language

List Processing – LISP (or LISP) is the second oldest high-level programming language after Fortran developed by John McCarthy in 1958 while he was at the Massachusetts Institute of Technology (MIT). LISP is a commonly used language for artificial intelligence (AI) programming.LISP has changed since its early days, and many dialects have existed over its history. Today, the best known general-purpose LISP dialects are Common LISP and Scheme.

There are two types of variables are available in LISP one is lexical variable, and other is special variable

LISP machines are general-purpose computers designed to efficiently run LISP as their main software and programming language, usually via hardware support. They are an example of a high-level language computer architecture, and in a sense, they were the first commercial single-user workstations.

LISP was invented by John McCarthy in 1958.

LISP stand for – List Processing – LISP (or LISP)

No

keyword argument are function arguments that are passed by keyword, instead of position.Keyword arguments can be mixed with by-position arguments, and default-value expressions can be supplied for either kind of argument:

(define greet
  (lambda (given #:last surname)
    (string-append "Hello, " given " " surname)))
 
> (greet "John" #:last "Smith") 
"Hello, John Smith"
> (greet #:last "Doe" "John")
"Hello, John Doe"

In above example last is a keyword argument.

* symbol is used to represent the prompt in LISP.

Prefix notation facilitates uniformity in LISP.
