Every serious programmer, or at least the one who wants to become one should read this book.
Book is supported with structured programming examples (Ada,C,Pascal), but the underlying principles that it is trying to present are as contemoporary as always.
I started my career as a programmer. As a novice I got to work on some (other people's) pretty crappy code that kept me up very long at night, and costed me a great deal of stress. Learning from that frustrating experience I asked myself - what is a good programming, and what would it take to learn how to be a great programmer/developer.
I discovered Steve McConnel's book, and it helped me a lot in getting there. It remained one of the milestones of my career.
This book will teach you a lot. It will show you a bad way to code, and the good way to do it. It will give you a great coding tips, and it will show you some, as the author calls them, "coding horrors". Moreover, it will tell you some great 80/20 rules that should help you with debugging, testing and refactoring focus.
It will definitely change you as a programmer - a lot. Do I need to say again that every serious programmer should read this book.
The only thing that I could wish for would be a reflection on
Object-Oriented programming and its good vs. bad practices.
