Last Updated :

In this article, we will discuss lambda functions in LISP. The Lambda function is used to evaluate a mathematical expression in our program. They are also known as anonymous functions.
We can create these functions using lambda expression.
Syntax:
(lambda (parameters) expression_code)
where,
- The parameters are the numbers of operands in the expression
- The expression_code is the mathematical logic expression
Example 1: LISP program to evaluate the mathematical expression through a lambda expression
Lisp
;lambda expression to get sum of product of four numbers
;mathematical expression is (val1*val2) + (val3*val4)
(write ((lambda (val1 val2 val3 val4)
(+ (* val1 val2) (+ (* val3 val4))))
;pass the values
2 4 6 8)
)
(terpri)
(write ((lambda (val1 val2 val3 val4)
(+ (* val1 val2) (+ (* val3 val4))))
;pass the values
10 20 30 40)
)
|
Output:
56
1400
Example 2: LISP Program to evaluate an expression
Lisp
;lambda expression to get product of two numbers
;mathematical expression is (val1*val2)
(write ((lambda (val1 val2 )
(* val1 val2))
;pass the values
60 4 )
)
(terpri)
(write ((lambda (val1 val2 )
(* val1 val2))
;pass the values
10 20 )
)
|
Output:
240
