LISP was invented by John McCarthy in 1958. It is high level programming language. It was first implement by Steve Russell on an IBM 704 Computer. Features of LISP 1. It is based on expressions. the prefix notations are used to represent the expression. 2. It has advanced object oriented features. 3. It has got automatic garbage collection. Hence the programmer need not have to explicitly free the dynamically allocated memory. 4. A strong support for recursion in programs. Due to this feature this language is widely used and accepted in artificial intelligence. 5. All computation is performed by applying functions to arguments. Variable declarations are rarely used. Applications Areas LISP is mainly used in:- 1.Artificial intelligence robotics. 2.Computer games. 3.Pattern Recognition. 4.Real time embedded systems 5.list handling and processing 6.for creating applications for educational purpose. 7.For List handling and processing. ::::::::::::::
