ISO/IEC – Programming languages — C++
The member functions of such an abstract base class are normally explicitly defined in the derived class, not inherited 144882. However Brian Kernighanalso a colleague at Bell Labs, disputes this assessment: Retrieved 8 July 22003, David ; Gurtovoy, Aleksey. Also see Can I write “void main “? Other complaints may include a lack of reflection or garbage collectionslow compilation times, perceived feature creep iiec,  and verbose error messages, particularly from template metaprogramming.
In some cases, exceptions cannot be used due to technical reasons. Initially, Stroustrup’s “C with Classes” added features to the C compiler, Cpre, including classesderived classesstrong typinginlining and default arguments.
This code is copied directly from Bjarne Stroustrup’s errata page p.

A public member of the class is accessible to any function. Stroustrup interviewed by Sergio De Simone 30 April This cannot be determined with exceptions as no tools exist to determine the maximum time required for an exception to be handled. Templates are different from macros: Some substitutions are not possible; these are eliminated by an overload resolution policy described by the phrase ” Substitution failure is not an error ” SFINAE.
1482 a function is called with fewer arguments than there are declared parameters, explicit arguments are matched to parameters in left-to-right order, with any unmatched parameters at the end of the parameter list being assigned their default arguments. A virtual member function is sometimes called a method. If the parent is an “automatic object” then it will be destroyed when it goes out of scope which triggers the destruction of all its members.
Retrieved 7 September Template use may increase code size, because each template instantiation produces a copy of the template code: The other two forms are much less frequently used.
Only public inheritance corresponds to what is usually meant by “inheritance”. And he sort of ran all the standards committees with a whip and a chair. Nonetheless a situation may arise where a copy of an object needs to be created when a pointer to a derived object is passed as a pointer to a base object.

Rules and Guidelines for Writing Programs. Retrieved 16 January And I think it suffered drastically from that. As part of the standardization 0203, ISO also publishes technical reports and specifications:. More technical specifications are in development and pending approval, including concurrency library extensions, a networking standard library, ranges, and modules.
Doing so allows the parameters with defaults to 18482 be omitted when the function is called, in which case the default arguments will be used.
Static storage duration objects are created before main is entered see exceptions below and destroyed 148822 reverse order of creation after main exits. Templates are a tool for static polymorphism see below and generic programming.
Virtual inheritance ensures that only one instance of a base class exists in the inheritance graph, avoiding some of the ambiguity problems of multiple inheritance.
Hence, at compile time, it may not 144882 possible to determine the type of the object and therefore the correct function to call, given only a base class pointer; the decision is therefore put off until runtime. It has imperativeobject-oriented and 1882 programming features, while also providing facilities for low-level memory manipulation. Member variables are created when the parent object is created. Any derived class inherits the virtual function as pure and must 41882 a non-pure definition of it and all other pure virtual functions before objects of the derived class can be created.
These objects have a dynamic lifespan and are created with a call to new and destroyed explicitly with a call to delete. The dynamic initialization order is defined as the order of declaration within the compilation unit i.
Some other languages, such as C or Java 2003, accomplish something similar although more limited by allowing inheritance of 148882 interfaces while restricting the number of base classes to one interfaces, unlike classes, provide only declarations of member functions, no implementation or member data. Encapsulation is the hiding of information to ensure that data structures and operators are used as intended and to make the usage model more obvious to the developer. It was designed with a bias toward system programming and embeddedresource-constrained and large systems, with performanceefficiency iiec flexibility of use as its design highlights.
The exception causes the current scope to be 200, and also each outer scope propagation until a suitable handler is found, calling in turn the destructors of any objects in these exited scopes. Retrieved 16 September It is generally considered good practice to make all data private or protected, and to make public only those functions that are part of a minimal interface for users of the class.
Virtual member functions or methods  allow the most specific implementation of the function to be called, according to the actual run-time type of the object. Classes Exception handling Function overloading new and delete Operator overloading Operators Templates.
Retrieved 7 February They are created and potentially initialized at the point of declaration see below for details and destroyed in the reverse order of creation when the scope is left. Interview with Ken Thompson”.
ISO standards by standard number. Alexandrescu, Andrei ; Sutter, Herb The exact order of creation is not specified by the standard though there are some rules defined below to allow implementations some freedom in how to organize their implementation.
A private member is accessible only to functions that are members of that class and to functions and classes explicitly granted access permission by the class “friends”. Retrieved 27 December The functions are distinguished by the number or types of their formal parameters. Journal 22003 Computing Sciences in Colleges.
