Description
This is 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.
