1 A Type Is A Set When you declare that a variable has a certain type you are saying that the values the variable can have are elements of a certain set A type is a set of values plus a lowlevel representation. Chapter Eight. Modern Programming Languages, 2nd ed.. 1. Introduction. Compare these function types.

Programming language syntax: how programs look, their form and structure. Syntax is defined using a kind of formal grammar. Programming language semantics: what programs do, their behavior and meaning. Modern Programming Languages, 2nd ed.. 1. Which Is Faster?. Every experienced programmer has a cost model of the language: a mental model of the relative costs of various operations. Not usually a part of a language specification, but very important in practice. Chapter 12: Computer Programming. 2. Chapter Contents. Section A: Programming Basics.
