Recursion is a powerful programming technique. A function that calls itself recursively not only saves programming effort and avoids repetition but it can also be used to navigate complex structures such as Trees and Class Hierarchies. This book explains both the theory and the practice of recursion with numerous short programs written in C, Ruby and C#. However, you don’t need to program in those languages to follow this book. The techniques explained in The Little Book Of Recursion can be applied to any mainstream programming language.

This book explains...

Recursive Functions
The Call Stack
Stack Frames
Stack Corruption
Recursion and Scope
Fibonacci Recursion
Infinite Recursion
Navigating Tree Structures
Disk Directory Recursion
Examples in C, Ruby, C#

The Little Book Of Recursion guides you step-by-step towards a deep understanding of using recursive functions and techniques, no matter which programming language you are using. It is illustrated throughout. By the time you finish this book, you will understand how recursion works and how to use recursive functions efficiently and safely. Whether you are studying computer science or whether you are a working programmer who needs a deeper understanding of recursion, this book explains what you need to know quickly and simply.

Each topic is explained with code examples. All the source code is provided as a free download from the publisher's web site.
