To add MD5 hash value, use hex_md5(). Let us first create a collection with documents −>db.addMd5HashValueDemo.insertOne({"UserName":"Adam", "UserPassword":"Adam123456"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6a4c66d78f205348bc619") } >db.addMd5HashValueDemo.insertOne({"UserName":"Chris", "UserPassword":"Chris_121#"}); { "acknowledged" : true, "insertedId" : ObjectId("5cd6a4e46d78f205348bc61a") }Following is the query to display all documents from a collection with the help of find() method −> db.addMd5HashValueDemo.find();This will produce the following output −{ "_id" : ObjectId("5cd6a4c66d78f205348bc619"), "UserName" : "Adam", "UserPassword" : "Adam123456" } { "_id" : ObjectId("5cd6a4e46d78f205348bc61a"), "UserName" : "Chris", "UserPassword" : "Chris_121#" }Following is the query to add md5 hash value to mongo collection −> db.addMd5HashValueDemo.find().forEach( function(documentPass){ documentPass.Value ...

The HTML DOM Anchor password property set or return the password part of the href attribute value. The password part is entered by the user. If you want to display it, then it can be seen after the username and before the hostname i.e. https −//username −password@www.demo.com.Following is the syntax to set the password property −anchorObj.password = passwordFollowing is the syntax to return the password property −anchorObj.passwordLet us now see an example to implement the DOM Anchor password property −Example Live Demo Company Products Display password Display origin Display hreflang function display() { ...

A navigation bar appears at the top of an app screen. To read more about ithttps://developer.apple.com/designhttps://developer.apple.com/documentationGetting height of Navigation bar becomes important if you’ve multiple view controllers having different UI and requirement. It becomes hectic if you’re not aware how to get the height of the same or modify as per need. Let’s see how we can get the height of Navigation bar.import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let navBarHeight = UIApplication.shared.statusBarFrame.size.height + (navigationController?.navigationBar.frame.height ?? 0.0) print(navBarHeight) } }
For this, you can use ORDER BY DESC LIMIT. Let us first create a table −mysql> create table DemoTable -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(100) -> ); Query OK, 0 rows affected (0.59 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(Name) values('John'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable(Name) values('Sam'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable(Name) values('Carol'); Query OK, 1 row affected (0.34 sec)Display all records from the table using select statement −mysql> ...

In the crypt-arithmetic problem, some letters are used to assign digits to it. Like ten different letters are holding digit values from 0 to 9 to perform arithmetic operations correctly. There are two words are given and another word is given as answer of addition for those two words. As an example we can say that two words ‘BASE’ and ‘BALL’, and the result is ‘GAMES’. Now if we try to add BASE and BALL by their symbolic digits, we will get the answer GAMES.NOTE − There must be ten letters maximum, otherwise it cannot be solved.InputThis algorithm will take ...

In C we have seen different format specifiers. Here we will see another format specifier called %p. This is used to print the pointer type data. Let us see the example to get a better idea.Example#include main() { int x = 50; int *ptr = &x; printf("The address is: %p, the value is %d", ptr, *ptr); }OutputThe address is: 000000000022FE44, the value is 50
This is a C++ program to perform finite state automaton based search. An automaton with a finite number of states is called a Finite Automaton. Here, a text is given text[0 … t-1] and a pattern p[0 ... p-1] is also given. We have to find the pattern in the text and print its all occurrences at the respective indices.AlgorithmsBegin Function void transitiontable(): 1) put the entries in first row and filled it up. All entries in first row are always 0 except the entry for p[0] character. Always we need to go to state 1. for ... Read More

Here we will see how to make timer using C++. Here we are creating one class called later. This class has following properties.int (milliseconds to wait until to run code)bool (If this is true, it returns instantly, and run the code after specified time on another thread)The variable arguments (exactly we want to feed to std::bind)We can change the chrono::milliseconds to nanoseconds or microseconds etc. to change the precision.Example Code#include #include #include #include class later { public: template later(int after, bool async, callable&& f, arguments&&... args){ ...
