His books help beginning students understand the important details necessary to become skilled programmers at an introductory level.

Gaddis motivates the study of both programming skills and the C++ programming language by presenting all the details needed to understand the "how" and the "why"-but never losing sight of the fact that most beginners struggle with this material.

His approach is gradual and highly accessible, ensuring that students understand the logic behind developing high-quality programs. As with all Gaddis texts, clear and easy-to-read code listings, concise and practical real-world examples, and an abundance of exercises appear in every chapter.

Updates to the 9th Edition include revised, improved problems throughout and a new chapter featuring completely rewritten and expanded material on the Standard Template Library (STL).
