Code Complete: Design in Construction. This book provides the objective information you need to make good decisions about your specific circumstances. Numerous code examples The book contains almost examples of good and bad code. I think other programmers learn best that way too. The examples are in multiple languages because mastering more than one language is often a watershed in the career of a professional programmer.
Once a programmer realizes that programming principles transcend the syntax of any specific language, the doors swing open to knowledge that truly makes a difference in quality and productivity. To access information related to Code Complete, 2d ed.

Why This Handbook Was Written The need for development handbooks that capture knowledge about effective development practices is well recognized in the software-engineering community. A report of the Computer Science and Technology Board stated that the biggest gains in software-development quality and productivity will come from codifying, unifying, and distributing existing knowledge about effective software-development practices CSTB , McConnell a.
The board concluded that the strategy for spreading that knowledge should be built on the concept of software-engineering handbooks. The Topic of Construction Has Been Neglected At one time, software development and coding were thought to be one and the same.
But as distinct activities in the software-development life cycle have been identified, some of the best minds in the field have spent their time analyzing and debating methods of project management, requirements, design, and testing.
The rush to study these newly identified areas has left code construction as the ignorant cousin of software development. Discussions about construction have also been hobbled by the suggestion that treating construction as a distinct software development activity implies that construction must also be treated as a distinct phase. Construction Is Important Another reason construction has been neglected by researchers and writers is the mistaken idea that, compared to other software-development activities, construction is a relatively mechanical process that presents little opportunity for improvement.
Nothing could be further from the truth. Construction accounts for about 75 percent of the errors on small projects and 50 to 75 percent on medium and large projects. Any activity that accounts for 50 to 75 percent of the errors presents a clear opportunity for improvement.
Chapter 27 contains more details on these statistics. Some commentators have pointed out that although construction errors account for a high percentage of total errors, construction errors tend to be less expensive to fix than those caused by requirements and architecture, the suggestion being that they are therefore less important.
The claim that construction errors cost less to fix is true but misleading because the cost of not fixing them can be incredibly high. Researchers have found that small-scale coding errors account for some of the most expensive software errors of all time, with costs running into hundreds of millions of dollars Weinberg , SEN An inexpensive cost to fix obviously does not imply that fixing them should be a low priority.
Requirements can be assumed rather than developed; architecture can be shortchanged rather than designed; and testing can be abbreviated or skipped rather than fully planned and executed.
The need for a book about how to program effectively seemed obvious.
But I found that only a few books had been written about construction and then only on parts of the topic. Some were written by professors who were not working on production code.
The professors wrote about techniques that worked for student projects, but they often had little idea of how the techniques would play out in full-scale development environments. When art critics get together they talk about Form and Structure and Meaning. When artists get together they talk about where you can download cheap turpentine.
The discussion needed to be brought up to date for current programming languages, object-oriented programming, and leading-edge development practices.
It seemed clear that a book about programming needed to be written by someone who was knowledgeable about the theoretical state of the art but who was also building enough production code to appreciate the state of the practice. Author Note I welcome your inquiries about the topics discussed in this book, your error reports, or other related subjects. These warning signs could show up after construction error rate or during construction compiler warning, indications from your self or other that your program is hard to understand.
In addition to being my favorite section heading in the book, this principle emphasizes that iteration is appropriate at all points of the software development process. Requirements are rarely fixed in stone, bugs are always present, and developers can always find a better way to rewrite code.
Iteration gives all of these improvements a chance to actually make it into the product under development.
No one convention, process, or tool set is the be all and end all of software development. Developers should be wary of absolutes and try to avoid blind faith in the processes they use.
Solutions should be adapted to the problem at hand, not vice versa. The key to keeping an open mind and becoming effective and flexible is experimentation.
Be willing to try new things, measure the effectiveness of those experiments, and be willing to change based on the results.
Those are the high level principles. These principles occur over and over again through the seven parts of this book. The first part, titled "Laying the Foundation" discusses the general process of software development and the role of construction a. Construction is important, according to McConnell, because it is the only part of the software development process that absolutely must happen to produce a working software project.
Construction is also an area that, traditionally, has not has as much attention to it as other areas such as high level design or testing. However, McConnell stresses that all parts of the development process are important in creating a successful project and gives pointers throughout the text to resources that discuss other parts of the software development process in more depth.
He notes that pre-construction planning is particularly important since no amount of good construction and through testing can save a bad design. Section two is "Creating High-Quality Code". This section introduces a point emphasized again and again throughout the book.
Software's "Primary Technical Imperative" is managing complexity. High quality code exposes people reading it to consistent levels of abstraction separated by clear boundaries. Complexity is managed by minimizing the essential complexity one has to deal with at any given time and trying to keep accidental complexity from spreading throughout the code base.
High quality classes and routines provide consistent abstractions, document their assumptions, and check their invariants defensively; they fail sooner rather than later. Even a simple class or routine is worthwhile if it decreases the complexity of reading the code where it is used. One of the most practically useful facts I got out of Code Complete was learning about the "Pseudocode Programming Process".
This process is a way of developing code by starting with detailed pseudocode. When constructing a program, a developer should iteratively write pseudocode that is high level enough to be in the domain of the problem but low level enough for translation to real code to be nearly mechanical.
Developing pseudocode ensures that the developer understands the problem at a low enough level for implementation, encourages the programmer to think about error checking before implementing the nominal path through the code, may indicate what when to factor code into separate routines and suggest names for those routines.
Those parts of the high level pseudocode that the developer decides to leave in provide automatic, high level commenting of code. The third section is entitled "Variables" and discusses the effective use of variables. The chapters in this section discuss data initialization do it close as close to the declaration as possible , variable scope keep it as small as possible , limiting variables to a single purpose, effective variable names keep them specific, use a naming conventions , and tips for using fundamental and more complex data types.
Statements are covered in section four called, not surprisingly, "Statements". This section discusses methods for effectively organizing and using straight line code, conditionals, and loops as well as more exotic control structures such as exceptions, gotos, and various table driven control structures. This section discusses how deep nesting of control structures tends to make code complex. If possible, it should be avoided by restructuring the code or factoring the nested code into its own routine.
The more paths there are through a code fragment, the more complex it is; the number of paths a developer must consider at a single time should be minimized. Section five, "Code Improvements" discusses a mishmash of techniques for improving code.
It discusses software quality, collaboration, developer testing, debugging, refactoring, and code tuning. One key point of this section is that the goals of a certain construction project should be clear. Some goals are bound to go against each other, and if developers do not know which are most important, they will do a bad job of trying to optimize all of them at once.
The most obvious example of this tendency is that aggressive optimization may make code less readable and prevent beneficial refactorings.
This section also points out that code reviews, testing, debugging, refactoring, and code tuning all have the potential to improve code quality, but it is when they are used thoughtfully in unison that their potential is maximized.
