Module 15 Study Guide

Learning Objectives (Prolog, CPL Ch.16)

We are learning elementary Prolog to get a taste of declarative and logical programming. As with functional programming, declarative programming is an entirely different way of thinking about programming from what you are used to. It is also quite different from functional programming. Specifically, by the end of the module you should be able to

• Run and exit the swipl interpreter
• Create and load a Prolog program into the swipl interpreter
• Run queries in the swipl interpreter and understand the results
• Write Prolog facts using predicates and atoms
• Write Prolog rules using variables and recursion
• Understand how the Prolog interpreter’s inference engine works
• Write rules using the cut (!), the not predicate (\+), and the anonymous variable (_)
• Write test cases that can be run after a program is loaded
