What are function templates of C++?
Function templates. Function templates are special functions that can operate with generic types. This allows us to create a function template whose functionality can be adapted to more than one type or class without repeating the entire code for each type. In C++ this can be achieved using template parameters.
How many types of templates are there in C++ 17?

Explanation: Template function helps in writing functions that work with different types of parameters which is what polymorphism means i.e. using same function prototype to perform the same operations on different types of parameters.
What are function templates?
Function templates are similar to class templates but define a family of functions. With function templates, you can specify a set of functions that are based on the same code but act on different types or classes.
How are function templates implemented?
Implementing Template Functions Function templates are implemented like regular functions, except they are prefixed with the keyword template. Here is a sample with a function template.
What is function template in C++ with example?
Function Templates We write a generic function that can be used for different data types. Examples of function templates are sort(), max(), min(), printArray(). Know more on Generics in C++ CPP.
Which keyword is used to define a function template in C++?
Explanation: C++ uses template reserved keyword for defining templates.
What is the difference between function template and template function?
What is the difference between a template function and a function template? Function Template is the correct terminology (a template to instantiate functions from). Template Function is a colloquial synonym. So, there’s no difference whatsoever.
What can you do with MediaWiki templates?
And with the addition of templates, parser functions and the like, MediaWiki gains the ability to have almost unlimited customization of the page content. MediaWiki allows some HTML within wiki pages, but for the most part all formatting is done using the wikitext syntax.
How does the ParserFunctions extension help MediaWiki?
The ParserFunctions extension provides eleven additional parser functions to supplement the ” magic words “, which are already present in MediaWiki. (It may be configured to provide additional parser functions for string handling; these string functions are documented elsewhere .) All the parser functions provided by this extension take the form:
What’s the purpose of the syntax in MediaWiki?
It’s intended as a simpler alternative to HTML, and one that allows more standardization of display. MediaWiki syntax has caused a lot of angst, especially for new users, but it’s not all that difficult once you understand the basic rules.
How to make a paragraph break in MediaWiki?
Despite its generic name, “wikitext” refers specifically to MediaWiki’s markup language. Let’s go through the elements of wikitext. A single newline between two lines will be ignored. To make a paragraph break, you need two newlines, i.e. an empty line between the two paragraphs. More than one empty line will lead to a bigger gap.
