Assignment 4: A Scheme Expression Evaluator For this assignment, you are asked to write various Scheme .scm files. When it is time to submit your work, please put all these .scm files into a single folder named a4, and zip it into a compressed archive named a4.zip. Make sure to use exactly the same function […]

Assignment 3: Scheme Write all your solution code in a single file named a3.scm. Make sure to use exactly the same function names and arguments (otherwise the marking software will give you 0!). Please use MIT Scheme. You can (and probably should!) create helper functions for some of the questions. Some of the questions ask

An Expression Evaluator with Variables¶ In this assignment, your task is to create an expression evaluator in Scheme for arithmetic expressions containing variables. Part 1: Association Lists¶ An association list is a list of pairs, where a pair is a 2-element list of the form (key value). For example: (define pets ‘((cat 1) (dog 1) (fish 1) (cat 2) (fish 2))

Project 2: Again, the goal is to practice designing a large program, with multiple functions, using iterative refinement, and no specific directives from us as to how to represent data or how to break up the problem. You cannot do more than one Project Two. You CAN get extra credit by doing a harder project
