The Standard Template Library (STL) is a software library originally designed by Alexander Stepanov for the C++ programming language that influenced many parts of the C++ Standard Library. It provides four components called algorithms , containers , functions , and iterators .
The curiously recurring template pattern (CRTP) is an idiom, originally in C++, in which a class X derives from a class template instantiation using X itself as a template argument. [1] More generally it is known as F-bound polymorphism , and it is a form of F -bounded quantification .
[[Category:Character templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Character templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character.
This template situates a character or string in a block 1ic wide—the width of a Chinese character.This is useful for orienting non–full width characters in full width contexts.
The content of each box is specified using additional named parameters appended to the template call. Each box is three tiles wide and normally has a black border two pixels wide. Boxes can have any name that is a valid template parameter name, subject to a minimum of two alphabetical characters. Tiles are line drawing symbols used to connect ...
Since C++20, using auto or Concept auto in any of the parameters of a function declaration, that declaration becomes an abbreviated function template declaration. [4] Such a declaration declares a function template and one invented template parameter for each placeholder is appended to the template parameter list:
This template is used on many pages and changes may be widely noticed. ... —This template produces one row in a "family tree"-like chart consisting of boxes and ...
The use of templates as a metaprogramming technique requires two distinct operations: a template must be defined, and a defined template must be instantiated.The generic form of the generated source code is described in the template definition, and when the template is instantiated, the generic form in the template is used to generate a specific set of source code.
