Problem Statement

Create a function which takes in a number of arguments which are specified by name rather than (necessarily) position, and show how to call the function. If the language supports reordering the arguments or optionally omitting some of them, note this. Note: See also:

Source code in the racket programming language

#lang racket

(define (pizza sauce
               ;; mandatory keyword argument
               #:topping topping
               ;; optional keyword argument with default
               #:type [type "deep dish"])
  (printf "~a pizza with ~a sauce topped with ~a~n"
          type sauce topping))

(pizza "tomato" #:topping "onion")
(pizza #:topping "onion" "garlic" #:type "pan")
