",  the"Summary": "even bad code can function. But if the code isn ' t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources is lost because of poorly written code. But it doesn ' t has to be the that. the noted software expert Robert C. Martin presents a revolutionary paradigm with Clean CODE:A Handbook of Agile Software Craftsmanship. Martin have teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code "on the  Fly "into a book that would instill within you the values of a software craftsman and make you a better programmer-but only If you are at it. the What kind's work would you be doing? You'll be reading code-lots of code. And you'll be a challenged to think about what's right on that code, and what's wrong with it. More importantly, you'll be a challenged to reassess your professional values and your commitment to your craft. + Clean Code was divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study was an exercise in cleaning up code-of transforming a code base that have some problems into one so is sou nd and efficient. The third part was the PAYOFF:A single chapter containing a list of heuristics and "smells" gathered while creating the CA SE Studies. The result is a knowledge base that describes the the-think when we write, read, and clean code. - Readers'll come away from the This book understanding the How to tell the difference between good and bad codeBayi How to write good code and how to transform bad code into good code the How to create good names, good functions, good objects, and good classes the How to format code for maximum readability - How to implement complete error handling without obscuring code logic - How to unit Test and practice Test-driven development theThis book was a must for any developer, software engineer, project manager, team leads, or systems analyst with an interest In producing better code.
