Sorry to bother you.'' This works remarkably well you can even use non-programmersĪs listeners. Than a few sentences, followed by an embarrassed ''Never mind, I see what's Will often cause you to explain the bug to yourself.

The machine was tens of millions of miles away and much harder to fix.Īnother effective technique is to explain your code to someone else. So they were forced to deal with the problem later when Resets had occurred, but had been ignored because the engineers were working Realized that they had seen that problem before. Landing in July 1997 the spacecraft's computers tended to reset once a day or Track it down right away, since it may not happen again until it's too late.Ī famous example occurred on the Mars Pathfinder mission.

Have a full explanation, we'll know what to fix and, along the way, likely discoverīeing in too much of a hurry can hurt. So we must think backwards from the result to discover the reasons. Impossible occurred, and the only solid information is that it really did occur. The crashed program to determine what could have caused this.ĭebugging involves backwards reasoning, like solving murder mysteries. How could that happen? Reason back from the state of Now you know something of what happened, and Look at any debugging output before the crash if possible getĪ stack trace from a debugger. Experienced programmers would love to do the same,īut they know that, realistically, most problems are their own fault.įortunately, most bugs are simple and can be found with simple techniques.Įxamine the evidence in the erroneous output and try to infer how it could haveīeen produced.

Anyone who writes software will profit from the principles and guidance in The Practice of Programming.

Kernighan and Pike have distilled years of experience writing programs, teaching, and working with other programmers to create this book.

notation: choosing languages and tools that let the machine do more of the work.

style: writing code that works well and is a pleasure to read.

interfaces: using abstraction and information hiding to control the interactions between components.

design: balancing goals and constraints to decide which algorithms and data structures are best.

portability: ensuring that programs run everywhere without change.

performance: making programs faster and more compact.

testing: guaranteeing that software works correctly and reliably.

debugging: finding bugs quickly and methodically.

This book is full of practical advice and real-world examples in C, C++, Java, and a variety of special-purpose languages. The Practice of Programming covers all these topics, and more. At the same time, they must be concerned with issues like compatibility, robustness, and reliability, while meeting specifications. Programmers must also assess tradeoffs, choose among design alternatives, debug and test, improve performance, and maintain software written by themselves and others. The practice of programming is more than just writing code. 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.
