As suggested by rahilwazir, you can use a different URL that will give you JSON. var request = require(‘request’); request( ‘https://raw.githubusercontent.com/nodejs/nodejs.org/master/source/versions.json’, function(err, resp, json) { if (err) return console.error(err); var data = JSON.parse(json); // Do what you need here }; ); If you really want to scrape the HTML page you mentioned, you could use … Read more
Welcome to stackoverflow. It seems like you’re not using any loop inside your main method, so your program simply closes after it executed the last statement. You want to add something like: while (!”q”.equals(userChar) && !”Q”.equals(userChar)) { System.out.println(“Choose R for Rock, P for Paper, S for Scissors, or Q to Quit, and press Enter: “); … Read more
I am trying to answer the question from a database point of view. You have a table with one or more rows and every row has in the four columns either an ‘A’ or something else. For a given row (or for many rows) you want to get the number of columns that have an … Read more
You’re not passing the data from your index.html to game.html. So when you call this: <a href=”https://stackoverflow.com/questions/55249162/game.html” class=”button” id=”startCyber”>START</a> You’re loading a new page, which removes all of your existing variables – including ‘color1’. I see 2 options here: Make this a single-page web app. So when you click your START button, it hides the … Read more
Your best bet is to start with CSS grid. I’ve but together a minimal example here to show you how it would work. <div class=”grid”> <div> hi </div> <div> hi </div> <div> hi </div> <div> hi </div> </div> Then for your css: div.grid { display: grid; grid-template-columns: repeat(4, 1fr); grid-gap: 8px; } div div { … Read more
It depends how complicated you’re going, it’d be easier to recommend if you had a specific project in mind. You could make a simple ‘GUI’ that just opens in a CMD/Terminal window with C++ and easily allow input (cin), changing what’s displayed as you desire. You could easily do your example this way, without the … Read more
Try: ControllerContext.Controller.ViewData.Model It’s not clear when exactly you need to fetch that data from the context, but you have to realize that the ViewModel returned to the View is only available after the OnResultExecuting event (same method on ActionFilter as well). solved get viewModel from the controllerContext MVC [closed]
Regex is the wrong tool for handling HTML (or XML) 99.9% of the time. Instead, use a parser, like Nokogiri: require ‘nokogiri’ html=”<img src=”https://filin.mail.ru/pic?width=90&height=90&email=multicc%40multicc.mail.ru&version=4&build=7″ style=””>” doc = Nokogiri::HTML(html) url = doc.at(‘img’)[‘src’] # => “https://filin.mail.ru/pic?width=90&height=90&email=multicc%40multicc.mail.ru&version=4&build=7” doc.at(‘img’)[‘style’] # => “” Once you’ve retrieved the data you want, such as the src, use another “right” tool, such as … Read more

i and id are both local variables with automatic storage (commonly referred to as on the stack). No new instances are created upon each iteration of the loop, the same space is reused and a new value is stored in id, hence the same addresses printed by printf. Note that the value of id is … Read more
The problem is int8_t is implemented as char. The implementation of the input stream is working like this: char x; std::string inputString = “abc”; std::istringstream is(inputString); is >> x; std::cout << x; The result is ‘a’, because for char the input stream is read char for char. To solve the problem, provide a specialised implementation … Read more
The main problem I see with your code is the reading loop, it has mainly two issues Read: Why is while (!feof(rPtr)) always wrong. You must check the return value of scanf(), and prevent scanf()‘s from overflowing the destination buffer, so the loop condition should be while (fscanf(rPtr, “%14s%lf%lf%lf”, fromDb.name, &fromDb.dArea, &fromDb.dLength, &fromDb.dFormFactor) == 4) … Read more
Try this code: a = input(“enter first number\n”) b= input(“enter second number\n”) limit=[] limit.append(a) limit.append(b) natNo=range(1,1000) xyz = [] for i in limit: xyz +=filter(lambda x: x == i or x % i==0, natNo) set = {} map(set.__setitem__, xyz, []) nums=set.keys() print “the multiples of the given numbers are: “+str(nums) c=reduce(lambda x, y:x+y, nums) print … Read more
