The usage of a function template saves space in the source code file in addition to limiting changes to one function description and making the code easier to read. An instantiated function template usually produces the same object code, though, compared to writing separate functions for all the different data types used in a specific program.
The template to the right includes links to alphabetical lists of all mathematical articles. This article brings together the same content organized in a manner better suited for browsing. Lists cover aspects of basic and advanced mathematics, methodology, mathematical statements, integrals, general concepts, mathematical objects, and reference ...
A template processor (also known as a template engine or template parser) is software designed to combine templates with data (defined by a data model) to produce resulting documents or programs. [ 1 ] [ 2 ] [ 3 ] The language that the templates are written in is known as a template language or templating language .
[12] [10] [13] [11] Repeated composition of such a function with itself is called function iteration. By convention, f 0 is defined as the identity map on f 's domain, id X . If Y = X and f : X → X admits an inverse function f −1 , negative functional powers f − n are defined for n > 0 as the negated power of the inverse function: f − n ...
One of the cited main motivations for the decltype proposal was the ability to write perfect forwarding function templates. [9] It is sometimes desirable to write a generic forwarding function that returns the same type as the wrapped function, regardless of the type it is instantiated with.
C++11 is a version of a joint technical standard, ISO/IEC 14882, by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), for the C++ programming language.
Alignment specification (_Alignas specifier, _Alignof operator, aligned_alloc function, <stdalign.h> header) The _Noreturn function specifier and the <stdnoreturn.h> header; Type-generic expressions using the _Generic keyword. For example, the following macro cbrt(x) translates to cbrtl(x), cbrt(x) or cbrtf(x) depending on the type of x:
