Overview

Designed for an introductory course, this text encapsulates the topics essential for a freshman course on compilers. The book provides a balanced coverage of both theoretical and practical aspects. The text helps the readers understand the process of compilation and proceeds to explain the design and construction of compilers in detail. The concepts are supported by a good number of compelling examples and exercises.
