JSON structure can be created with the below code −$json = json_encode(array( "client" => array( "build" => "1.0", "name" => "xxxx", "version" => "1.0" ), "protocolVersion" => 4, "data" => array( "distributorId" => "xxxx", "distributorPin" => "xxxx", "locale" => "en-US" ) ));

The usort function can be used to sort a multidimensional array. It sorts with the help of a user defined function.Below is a sample code demonstration −Examplefunction compare_array($var_1, $var_2) { if ($var_1["price"] == $var_2["price"]) { return 0; } return ($var_1["price"] < $var_2["price"]) ? -1 : 1; } usort($my_Array,"compare_array") $var_1 = 2 $var_2 = 0OutputThis will produce the following output −1Explanation − We have declared var_1 and var)2 with integer values. They are compared and the result is returned.
To get the list of files in a directory, use the SearchOptions.AllDirectories in C#.Firstly, set the directory for which you want the files −string[] myFiles = Directory.GetFiles("D:\New\", "*.*", SearchOption.AllDirectories);The following is an example displaying files from the above mentioned directory −Exampleusing System; using System.Linq; using System.IO; class Program { static void Main() { string[] myFiles = Directory.GetFiles("D:\New\", "*.*", SearchOption.AllDirectories); foreach (string res in myFiles) { Console.WriteLine(res); } } }OutputThe following is the output. It lists all the directories of the folder −D:\New\one.txt D:\New\two.html D:\Newature.png
FileInfo type has a Length property that determines how many bytes a file has.Firstly, set the file −FileInfo file = new FileInfo("D:ew");Now use the Length property −file.LengthHere is the complete code −Exampleusing System; using System.Linq; using System.IO; class Program { static void Main() { FileInfo file = new FileInfo("D:ew"); long res = file.Length; Console.WriteLine("Bytes: "+res); } }OutputThe following is the output −3259244
Java 9 has introduced JShell for Java, and it allows us to evaluate code snippets such as declarations, statements, and expressions.During the JShell session, we need to reset it without closing and re-opening JShell then we can use the internal command: "/reset". By using this command, code entered during the current session has erased. It can be useful when we want to test new classes, create new variables, etc. while keeping the names previously used.In the below snippet, we have created variables x, y, and str. We can able to see all entered code snippets using the "/list" command. After that, we can apply ... Read More
A value can be converted into a string with the help of (string) cast or the strval() function.The strval() function is a function call whereas (string) cast is an internal type casting method.Unless there is some specific dataset or use case, both of these can be used interchangeably.This is because PHP uses automatic type conversion, due to which a variable's type is determined based on the context in which it is used.The strval($var) function returns the string value of $var whereas the (string)$var explicitly converts the "type" of $var during the process of evaluation.The $var can be any scalar type ...

When performing an operation in the JShell tool, it displays a message in return (success of the command, error, and type of a variable created as well as its value). It has been customized using the command: "/set feedback". This command displays the type of return currently configured as well as the different return modes available.jshell> /set feedback | /set feedback normal | | Available feedback modes: | concise | normal | silent | verboseThere are four feedback modes available in JShell as listed below:1) /set feedback normal: This is the default JShell feedback. When we evaluate an expression, JShell returns the corresponding result and an ... Read More
In this tutorial, we will be discussing a program to get maximum of all subarrays of size k using set in C++ STL.For this we will be provided with a array of size N and integer K. Our task is to get the maximum element in each K elements, add them up and print it out.Example Live Demo#include using namespace std; //returning sum of maximum elements int maxOfSubarrays(int arr[], int n, int k){ set q; set::reverse_iterator it; //inserting elements for (int i = 0; i < k; i++) { q.insert(pair(arr[i], i)); } ...

In this tutorial, we will be discussing a program to create a menu driven program for a simple calculator.This program will give user the ability to choose among the following mathematical operations − addition, subtraction, multiplication, division, HCF and LCM.Example Live Demo#include using namespace std; //displaying the menu void menu(){ cout
