Seth D. Bergmann wrote:This book is a revision of an earlier edition that was written for a Pascal based curriculum. As many computer science departments have moved to C++ as the primary language in the undergraduate curriculum, I have produced this edition to accommodate those departments. This book is not intended to be strictly an object-oriented approach to compiler design. 

The most essential prerequisites for this book are courses in C or C++ programming, Data Structures, Assembly Language or Computer Architecture, and possibly Programming Languages. If the student has not studied formal languages and automata, this book includes introductory sections on these theoretic topics, but in this case it is not likely that all seven chapters will be covered in a one semester course. Students who have studied the theory will be able to skip the preliminary sections (2.0, 3.0, 4.0) without loss of continuity.
