A new edition of a textbook that provides students with a deep, working understanding of the essential concepts of programming languages, completely revised, with significant new material. This book provides students with a deep, working understanding of the essential concepts of programming languages. Most of these essentials relate to the semantics, or meaning, of program elements, and the text uses interpreters (short programs that directly analyze an abstract representation of the program text) to express the semantics of many essential language elements in a way that is both clear and executable. The approach is both analytical and hands-on. The book provides views of programming languages using widely varying levels of abstraction, maintaining a clear connection between the high-level and low-level views. Exercises are a vital part of the text and are scattered throughout; the text explains the key concepts, and the exercises explore alternative designs and other issues. The complete Scheme code for all the interpreters and analyzers in the book can be found online through The MIT Press web site. For this new edition, each chapter has been revised and many new exercises have been added. Significant additions have been made to the text, including completely new chapters on modules and continuation-passing style. Essentials of Programming Languages can be used for both graduate and undergraduate courses, and for continuing education courses for programmers.

This textbook offers an understanding of the essential concepts of programming languages. The text uses interpreters, written in Scheme, to express the semantics of many essential language elements in a way that is both clear and directly executable.

In-depth case studies of representative languages from five generations of programming language design (Fortran, Algol-60, Pascal, Ada, LISP, Smalltalk, and Prolog) are used to illustrate larger themes."--BOOK JACKET.

Beside the computers itself, programming languages are the most important tools of a computer scientist, because they allow the formulation of algorithms in a way that a computer can perform the desired actions. Without the availability of (high level) languages it would simply be impossible to solve complex problems by using computers. Therefore, high level programming languages form a central topic in Computer Science. It should be a must for every student of Computer Science to take a course on the organization and structure of programming languages, since the knowledge about the design of the various programming languages as well as the understanding of certain compilation techniques can support the decision to choose the right language for a particular problem or application. This book is about high level programming languages. It deals with all the major aspects of programming languages (including a lot of examples and exercises). Therefore, the book does not give an detailed introduction to a certain program ming language (for this it is referred to the original language reports), but it explains the most important features of certain programming languages using those pro gramming languages to exemplify the problems. The book was outlined for a one session course on programming languages. It can be used both as a teacher's ref erence as well as a student text book.

A comprehensive introduction to type systems and programming languages. A type system is a syntactic method for automatically checking the absence of certain erroneous behaviors by classifying program phrases according to the kinds of values they compute. The study of type systems—and of programming languages from a type-theoretic perspective—has important applications in software engineering, language design, high-performance compilers, and security. This text provides a comprehensive introduction both to type systems in computer science and to the basic theory of programming languages. The approach is pragmatic and operational; each new concept is motivated by programming examples and the more theoretical sections are driven by the needs of implementations. Each chapter is accompanied by numerous exercises and solutions, as well as a running implementation, available via the Web. Dependencies between chapters are explicitly identified, allowing readers to choose a variety of paths through the material. The core topics include the untyped lambda-calculus, simple type systems, type reconstruction, universal and existential polymorphism, subtyping, bounded quantification, recursive types, kinds, and type operators. Extended case studies develop a variety of approaches to modeling the features of object-oriented languages.

"Friedman, Wand, and Haynes have done a landmark job... The sample interpreters in this book are outstanding models. Indeed, since they are runnable models, I'm sure that these interpreters will find themselves at the cores of many programming systems over the years." --from the foreword by Hal Abelson What really happens when a program runs? "Essentials of Programming Languages" teaches the fundamental concepts of programming languages through numerous short programs, or "interpreters, " that actually implement the features of a language. Nearly 300 exercises using these programs provide a hands-on understanding of programming principles that is hard, if not impossible, to achieve by formal study alone. In an approach that is uniquely suited to mastering a new level of programming structure, the authors derive a sequence of interpreters that begins with a high-level operational specification (close to formal semantics) and ends with what is effectively assembly language--a process involving programming transformation techniques that should be in the toolbox of every programmer. The first four chapters provide the foundation for an in-depth study of programming languages, including most of the features of Scheme, needed to run the language-processing programs of the book. The next four chapters form the core of the book, deriving a sequence of interpreters ranging from very high- to very low-level. The authors then explore variations in programming language semantics, including various parameter-passing techniques and object-oriented languages, and describe techniques for transforming interpreters that ultimately allow the interpreter to beimplemented in any low-level language. They conclude by discussing scanners and parsers and the derivation of a compiler and virtual machine from an interpreter. More on "Essentials of Programming Languages"

This clearly written textbook introduces the reader to the three styles of programming, examining object-oriented/imperative, functional, and logic programming. The focus of the text moves from highly prescriptive languages to very descriptive languages, demonstrating the many and varied ways in which we can think about programming. Designed for interactive learning both inside and outside of the classroom, each programming paradigm is highlighted through the implementation of a non-trivial programming language, demonstrating when each language may be appropriate for a given problem. Features: includes review questions and solved practice exercises, with supplementary code and support files available from an associated website; provides the foundations for understanding how the syntax of a language is formally defined by a grammar; examines assembly language programming using CoCo; introduces C++, Standard ML, and Prolog; describes the development of a type inference system for the language Small.

A Web-Based Introduction to Programming is designed for use in introductory programming, programming logic and design, or Web programming courses, and for anyone seeking a painless way to learn the basics of programming by developing small Web applications. The book is clearly written, using consistent examples in every chapter and step-by-step descriptions of standard programming procedures. Each chapter follows precise learning outcomes that are accurately tested by the end-of-chapter quizzes and exercises. A Web-Based Introduction to Programming keeps the focus on the need for beginning programmers to learn essential syntax and control structures with minimal complexity. Each chapter focuses on a single topic and related material is provided in appendices. Students learn to convert requirements into algorithms, and then develop small Web-based applications using a combination of PHP and HTML. The chapter code exercises are designed to skill and confidence step-by-step: Fixit exercises provide small programs that include a single error of some kind and help students develop their problem-solving abilities and debugging skills. Modify exercises provide working programs that must be modified to perform a somewhat different or additional function. These exercises test student's ability to read, understand, and adapt existing code. Code completion exercises allow students to apply all concepts and tools covered in the chapter by developing new applications. All required software is provided and can be installed quickly and easily in minutes under Windows, Macintosh OS X or Linux. The software can be installed entirely on a USB drive so that students can carry their entire work environment with them (no need for special classroom installation). Significant changes to the second edition include: the latest version of the standalone Web server; even more code examples; additional code exercises for each chapter; flow chart examples to help explain control structures; more in-depth coverage of associative arrays and Web sessions; more extensive discussion of include files; additional references to emerging technologies. The Web site www.mikeokane.com/textbooks/WebTech/ includes all materials found on the CD, and also provides access to additional exercises, test banks, slide presentations, quiz solutions, code solutions, and other instructional resources. "This is the best logic book I have ever had in over 25 years of teaching!" -- Bob Husson, Craven Community College "I teach intro to programming and algorithms and I have used this book for three terms. It is excellent. The book's content leads students through the examples in a natural way that makes learning traditional programming concepts easy and students retain the concepts. The coding exercises build upon each other from algorithms all the way through small PHP programs. As a teacher I highly recommend this book for students and instructors alike." --Charlie Wallin, Asheville-Buncombe Technical Community College "The textbook, A Web-Base Introduction to Programming, was my first exposure to PHP. I could not have asked for a better introduction. The explanations, examples, and order of topics covered, made teaching and learning the basics of PHP a simple process. My students found the exercises and assignments at the end of each chapter fun but challenging. My only regret is that I did not discover this book sooner." -- Joe Sherrill, Martin Community College (retired)
