With the same insight and authority that made their book The Unix Programming Environment a classic, Brian Kernighan and Rob Pike have written The Practice of Programming to help make individual programmers more effective and productive.

The practice of programming is more than just writing code. Programmers must also assess tradeoffs, choose among design alternatives, debug and test, improve performance, and maintain software written by themselves and others. At the same time, they must be concerned with issues like compatibility, robustness, and reliability, while meeting specifications.

The Practice of Programming covers all these topics, and more. This book is full of practical advice and real-world examples in C, C++, Java, and a variety of special-purpose languages. It includes chapters on:

• debugging: finding bugs quickly and methodically
• testing: guaranteeing that software works correctly and reliably
• performance: making programs faster and more compact
• portability: ensuring that programs run everywhere without change
• design: balancing goals and constraints to decide which algorithms and data structures are best
• interfaces: using abstraction and information hiding to control the interactions between components
• style: writing code that works well and is a pleasure to read
• notation: choosing languages and tools that let the machine do more of the work

Kernighan and Pike have distilled years of experience writing programs, teaching, and working with other programmers to create this book. Anyone who writes software will profit from the principles and guidance in The Practice of Programming .

Review:

Coauthored by Brian Kernighan, one of the pioneers of the C programming language, The Practice of Programming is a manual of good programming style that will help any C/C++ or Java developer create faster, more maintainable code.

Early sections look at some of the pitfalls of C/C++, with numerous real-world excerpts of confusing or incorrect code. The authors offer many tips and solutions, including a guide for variable names and commenting styles. Next, they cover algorithms, such as binary and quick sorting. Here, the authors show how to take advantage of the built-in functions in standard C/C++. When it comes to data structures, such as arrays, linked lists, and trees, the authors compare the options available to C, C++, Java, and even Perl developers with a random-text-generation program (using a sophisticated Markov chain algorithm) written for each language.

Subsequent sections cover debugging tips (including how to isolate errors with debugging statements) and testing strategies (both white-box and black-box testing) for verifying the correctness of code. Final sections offer tips on creating more portable C/C++ code, with the last chapter suggesting that programmers can take advantage of interpreters (and regular expressions) to gain better control over their code. A handy appendix summarizes the dozens of tips offered throughout the book.

With its commonsense expertise and range of examples drawn from C, C++, and Java, The Practice of Programming is an excellent resource for improving the style and performance of your code base. --Richard Dragan
