Every software development team should have and follow a coding standard.It's even better when what the coding standard requires is actually consistent,reasonable, and correct.Coding standards have many advantages:*They improve code quality. This happens automatically when following agood, simple set of guidelines.*They improve development speed, because the programmer doesn't need toalways make decisions starting from first principles.*They enhance teamwork by eliminating needless debates on inconsequentialissues and by making it easy for teammates to read and maintain each other'scode.The coding standards introduced by this book are a collection of guidelines forwriting high-quality C++ code.***They are the distilled conclusions of a rich collective experience of the C++community. Until now, this body of knowledge has been available only asfolklore or spread in bits and pieces throughout books.

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
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
Hide information
Know when and how to code for concurrency
Ensure resources are owned by objects. Use explicit RAII and smart pointers
Coding Style
Prefer compile- and link-time errors to run-time errors
Use const proactively
Avoid macros
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
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 &&, [double vertical line], or, (comma)
Don't write code that depends on the order of evaluation of function arguments
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-style structs)
Don't give away your internals
Pimpl judiciously
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)
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)
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
Templates and Genericity
Blend static and dynamic polymorphism judiciously
Customize intentionally and explicitly
Don't specialize function templates
Don't write unintentionally nongeneric code
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
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
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
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
