C++ Coding Standards: 101 Rules, Guidelines, and Best Practices (英语) 平装 – 2004年11月4日
Herb Sutter is the author of three highly acclaimed books, Exceptional C++ Style, Exceptional C++, and More Exceptional C++ (Addison-Wesley). He chairs the ISO C++ standards committee, and is contributing editor and columnist for C/C++ Users Journal. As a software architect for Microsoft, Sutter leads the design of C++ language extensions for .NET programming.
Andrei Alexandrescu is the author of the award-winning book Modern C++ Design (Addison-Wesley, 2001) and is a columnist for C/C++ Users Journal.
1. Organizational and Policy Issues.
Don't sweat the small stuff. (Or: Know what not to standardize.).
Compile cleanly at high warning levels.
Use an automated build system.
Use a version control system.
Invest in code reviews.
2. Design Style.
Give one entity one cohesive responsibility.
Correctness, simplicity, and clarity come first.
Know when and how to code for scalability.
Don't optimize prematurely.
Don't pessimize prematurely.
Minimize global and shared data.
Know when and how to code for concurrency.
Ensure resources are owned by objects. Use explicit RAII and smart pointers.
3. Coding Style.
Prefer compile- and link-time errors to run-time errors.
Use const proactively.
Avoid magic numbers.
Declare variables as locally as possible.
Always initialize variables.
Avoid long functions. Avoid deep nesting.
Avoid initialization dependencies across compilation units.
Minimize definitional dependencies. Avoid cyclic dependencies.
Make header files self-sufficient.
Always write internal #include guards. Never write external #include guards.
4. Functions and Operators.
Take parameters appropriately by value, (smart) pointer, or reference.
Preserve natural semantics for overloaded operators.
Prefer the canonical forms of arithmetic and assignment operators.
Prefer the canonical form of ++ and --. Prefer calling the prefix forms.
Consider overloading to avoid implicit type conversions.
Avoid overloading &&, , or , (comma).
Don't write code that depends on the order of evaluation of functionarguments.
5. Class Design and Inheritance.
Be clear what kind of class you're writing.
Prefer minimal classes to monolithic classes.
Prefer composition to inheritance.
Avoid inheriting from classes that were not designed to be base classes.
Prefer providing abstract interfaces.
Public inheritance is substitutability.
Inherit, not to reuse, but to be reused.
Practice safe overriding.
Consider making virtual functions nonpublic, and public functions nonvirtual.
Avoid providing implicit conversions.
Make data members private, except in behaviorless aggregates (C-stylestructs).
Don't give away your internals.
Prefer writing nonmember nonfriend functions.
Always provide new and delete together.
If you provide any class-specific new, provide all of the standard forms (plain, in-place, and nothrow).
6. Construction, Destruction, and Copying.
Define and initialize member variables in the same order.
Prefer initialization to assignment in constructors.
Avoid calling virtual functions in constructors and destructors.
Make base class destructors public and virtual, or protected and nonvirtual.
Destructors, deallocation, and swap never fail.
Copy and destroy consistently.
Explicitly enable or disable copying.
Avoid slicing. Consider Clone instead of copying in base classes.
Prefer the canonical form of assignment.
Whenever it makes sense, provide a no-fail swap (and provide it correctly).
7. Namespaces and Modules.
Keep a type and its nonmember function interface in the same namespace.
Keep types and functions in separate namespaces unless they're specifically intended to work together.
Don't write namespace usings in a header file or before an #include.
Avoid allocating and deallocating memory in different modules.
Don't define entities with linkage in a header file.
Don't allow exceptions to propagate across module boundaries.
Use sufficiently portable types in a module's interface.
8. Templates and Genericity.
Blend static and dynamic polymorphism judiciously.
Customize intentionally and explicitly.
Don't specialize function templates.
Don't write unintentionally nongeneric code.
9. Error Handling and Exceptions.
Assert liberally to document internal assumptions and invariants.
Establish a rational error handling policy, and follow it strictly.
Distinguish between errors and non-errors.
Design and write error-safe code.
Prefer to use exceptions to report errors.
Throw by value, catch by reference.
Report, handle, and translate errors appropriately.
Avoid exception specifications.
10. STL: Containers.
Use vector by default. Otherwise, choose an appropriate container.
Use vector and string instead of arrays.
Use vector (and string::c_str) to exchange data with non-C++ APIs.
Store only values and smart pointers in containers.
Prefer push_back to other ways of expanding a sequence.
Prefer range operations to single-element operations.
Use the accepted idioms to really shrink capacity and really erase elements.
11. STL: Algorithms.
Use a checked STL implementation.
Prefer algorithm calls to handwritten loops.
Use the right STL search algorithm.
Use the right STL sort algorithm.
Make predicates pure functions.
Prefer function objects over functions as algorithm and comparer arguments.
Write function objects correctly.
12. Type Safety.
Avoid type switching; prefer polymorphism.
Rely on types, not on representations.
Avoid using reinterpret_cast.
Avoid using static_cast on pointers.
Avoid casting away const.
Don't use C-style casts.
Don't memcpy or memcmp non-PODs.
Don't use unions to reinterpret representation.
Don't use varargs (ellipsis).
Don't use invalid objects. Don't use unsafe functions.
Don't treat arrays polymorphically.

101 rules, mostly described in one or 2 pages make it a good reading before fall asleep, a good reminder of best practices that should not be forgotten. In these times, where code reviews are part of our daily activity, being aligned and focused makes the job more easy.
For novice it's for sure a good set of best-practices to be learned. For intermediate-expert it provides a clean and well focused reasoning on every single rule, good for tutoring and nice nuts of knowledge.
A must have.
I must say I'm a bit dissapointed. Not because this isn't a good book, which it is, but because it's not as good as the previous ones. It seems like the author didn't expect the readers from learn that much from the Exceptional C++ series... so he explains things that seem obvious if you read those book.
One example: "Don't memcpy or memcmp non-PODs". Who would ever do such as thing other than a newbie?
Anyway, if you are wondering whether or not you should buy this book: If you completed the previous ones (and made all the exercises), just don't. Not because is not good, but because you don't need it.
If you are fluent in C++ but by no means a guru yet, go for the book. Make an effort to revise a bit of your own code following its advice. You are likely to be surprised with the results.
