海外TECH	DEV Community	Design Patterns in PHP 8: Prototype	https://dev.to/zhukmax/design-patterns-in-php-8-prototype-1kg1	Design Patterns in PHP PrototypeDesign pattern Prototype give us control of making clones of objects In php syntax we have special keyword command clone for making object s copy But it does not allow you to clone correctly some parameters that are implementations of other classes I propose to consider an example that can be encountered when developing a blog or an online publication On such resources one of the main entity is the Page which of course has an author Let s implement this The author will have of course the name as well as the list of pages of this author In this case the list will contain not just an id but a full fledged page object class Author public function construct private readonly string name private array pages public function getName string return this gt name public function addPage Page page void this gt pages page public function getPages array return this gt pages Also each page must have an author property that implements the Author class In addition to other necessary data class Page public function construct private string title private string body private readonly Author author private array comments private DateTime date new DateTime this gt author gt addPage this public function getTitle string return this gt title public function setTitle string title void this gt title title public function getBody string return this gt body public function setBody string body void this gt body body public function getComments array return this gt comments public function addComment string comment void this gt comments comment public function getDate DateTime return this gt date Now with such a structure cloning pages becomes not an easy task for PHP And this may well be necessary if the author wants to make a copy of his article which in the future will publish a new one based on it It is for this situation that the Prototype template exists which allows you to configure exactly how to clone complex objects Let s add an implementation of the magic cloning method to the Page class in which we will describe exactly how we need to clone objects of this class public function clone this gt title Copy of this gt title this gt author gt addPage this this gt comments this gt date new DateTime Of course we can implement more complex logic in the method In practice the Page can refer to more other objects in its properties In such a case Prototype can be a very useful approach	2022-07-31 12:40:39

海外TECH	DEV Community	Can we pass a function to a function in C as a parameter?	https://dev.to/namantam1/can-we-pass-a-function-to-a-function-in-c-as-a-parameter-g79	Can we pass a function to a function in C as a parameter Whenever we work in high level languages like python and JavaScript we can pass functions as parameters to a function and call it there But is this also possible in low level languages like C C Yes This is also possible in C C but in a little different way We know that In C C we have access to memory addresses by pointers So using a pointer we can also point to a function the same as we do for array int char or any other data type So let s start with a very simple programCode include lt stdio h gt int add int a int b return a b function as param int do operation int operation int int int a int b return operation a b int main int argc char const argv printf d n do operation add return Output What s going on in function do operation in the above code The parameter int operation int int is the function signature with the name operation Let me explain more about it int operation int int left identifier rightidentifier function name operation left function return type int right params type function accept int int So we can declare a function like this return type function name param param But what if we have to use this function in multiple functions We will have to declare it like this everywhere No Here comes our life saver typedef We can typedef the function signature and use it anywhere For example we can declare our above function signature as typedef int operation int int int operation operation op int a int b return op a b Isn t this very simple and readable Source freepik comNow Let s take a complex example of how passing functions as parameters can be useful Code include lt stdio h gt Defining internal functions int multiply int a int b return a b int subtract int a int b return a b int add int a int b return a b Functions nametypedef enum ADD SUBTRACT MULTIPLY Operations declaring function typetypedef int function t int int struct to hold multiple functionstypedef struct Operations op char name function t fun Operation t Initialize functions arrayOperation t operations ADD Add add SUBTRACT Subtract subtract MULTIPLY Multiply multiply Function to do multiple operating by just function name void do operation Operations op int a int b for int i i lt sizeof operations sizeof Operation t i if op operations i op printf Operation s n operations i name printf Result d n n operations i fun a b return printf Invalid Operation n int main calling the with function name to perform operation do operation ADD do operation SUBTRACT do operation MULTIPLY return OutputOperation AddResult Operation SubtractResult Operation MultiplyResult From the above code We can observe that just by passing the function name we can execute it This article is highly inspired by the content provided by Jacob Sorber on his youtube channel ️Thank you so much for reading this article I m a passionate engineering student learning new things so If you find any mistakes or have any suggestions please let me know in the comments Also consider sharing and giving a thumbs up If this post helps you in any way	2022-07-31 12:01:00
