From the reviews of the second edition:

"Addressing mathematical concepts, algorithms and C/C++ code is not a simple task; the author handles them well throughout the book. This book is translated from German by David Kramer. … A well written book that addresses the intended purpose. … A beginner or intermediate level C/C++ programmer can follow the text." (S. Terai, SIGACT News, Vol. 39 (1), 2008)

Michael Welschenbach works for SRC Security Research & Consulting GmbH in Bonn, Germany. He graduated with a master's degree in mathematics from the University of Cologne, and has extensive experience in both pure and applied cryptological research. Currently, his favorite programming languages are C and C++. When not working, he enjoys spending time with his wife and two sons, programming, reading, and playing music.
