The document discusses the history and features of the Lisp programming language, created by John McCarthy, highlighting its foundations in functional programming and its use of list structures. It outlines the advantages, such as portability and ease of testing, as well as disadvantages, including limited popularity and difficulty of learning. Additionally, it mentions various applications of Lisp in fields like artificial intelligence, computer games, and air defense systems.

2. HISTORY OF LISP LANGUAGE
John Mccarthy
• A computer programming language
• Mathematical theory
• Functional Applied to data
• EXAMPLE: (+a(*bc))=a+b*c
• Uses the list structure
• Common language for AI
• Second Oldest High Level programming language
• Three basic building blocks(Atom, List, String)

3. LISP FEATURES
•S-expressionas the universaldata type
•FunctionalProgrammingstyle
•Uniform Representation of data andcode
•Relianceon Recursion
•GarbageCollection
•Machine Independent
•Specialforms
•Advanced oop A lisp machine at the MIT museum

4. EXAMPLE OF LISP
• TO Find the Maximum number of three using LISP
(defun max 3(a b c)
(cond((> a b)(cond((>a c)a)
(t c)))
((>b c)b)
(t c)))
Output
max3(2 3 4)

5. ADVANTAGES AND
DISADVANTAGES
• Easy to test
• Portable
• Syntax and semantics
• Modules
• Flexible
• Recursion
• Execution of other
programs
• Interaction
• Lack of popularity
• Limited Availability
• Requires multiple
interpreter
• Small install base
• Hard to learn
• Other programmers
