Programs in lisp with output

Q. Write a function in LISP that evaluate a fully parenthesized infix arithmetic  expression.

SOFTWARE USED:  LispWorks 6.1

THEORY:-

INFIX   EXPRESSIONS

Infix notation is the common arithmetic and logical formula notation, in which operators are written infix-style between the operands.

Example-

                       ( 2 + 3 )=5

PREFIX   EXPRESSIONS

Prefix notation is written in the form as the operator is placed before the operands.

Example-

                      ( + 2 3 )=5

In LISP programming we always write our code in prefix expression.

Example-

                      ( - 9 5 ) =4

SOURCE CODE ( IF INCLUDED )

( + 6 5 )

RESULT:-

CONCLUSION:-

We learned about writing the function to evaluate a fully parenthesized infix arithmetic expression.
