Higher Order Functions in Haskell Today: Lazy Evaluation Evaluation Strategy A programming language’s policy on when to compute an expression that is being passed as an argument Before being passed? Or after? Definitely going to evaluate? Or perhaps not? Eager/Strict/Applicative Order Evaluation All arguments are evaluated, and they are evaluated before passing them to a

PowerPoint Presentation Haskell! Intro to Haskell Named after logician Haskell Curry (1900-1982) A more modern functional language: created late 1980’s Many similarities with Racket: Programming with expressions, not statements – No mutation! Everything is immutable. Functions are values – Can be passed as parameters to and returned from functions Lists are the fundamental data structure
1. Name three different ways that the following code is “imperative.” 1) It mutates state, for example: myarray[firstPos] = myarray[otherPos] 2) To hold data it uses an array “myarray,” which is not a recursive data structure. 3) To accomplish repetitive computation, it iterates with a for loop. 2. Consider the following function definition: (define (fib
