[ad_1] Your question misses important details and actually I shouldnt be writing this answer, but as you actually also didnt ask a question, I just do it. This error message: error: no matching function for call to ‘AlgoStack<State<std::pair<int, int>* >>::push(State<std::pair<int, int> >*&)’ tells us that there is an instantiation of AlgoStack with the template parameter … Read more
[ad_1] Normally with recursion you’d have a function that calls itself. You don’t need recursion to reverse a string, but I suppose you could have a function that takes a string, and appends the first character of the string to the reverse of the rest. I’ll try to explain how this works without giving too … Read more
[ad_1] You are accidentally changing the entire dictionary instead of the specific alien you want the dictionary to represent. For now, just add .copy() to each time you append an alien dictionary to your random list of aliens. if color[random_num] == ‘green’: aliens_1.append(alien_0.copy()) In the future, this is probably best handled with classes rather than … Read more

[ad_1] First of all, echo is not a function, it is a language construct and it does not actually “return” anything. echo is for outputting strings. The reason it outputs (not returns) 1 instead of true is because true is not a string, it is a boolean value and therefore when it is typecast to … Read more
[ad_1] I have made an example how it could look with PDO (as i see you are just starting and i suggest to learn PDO as its not that hard) This way you also are safe from SQL injections. $host=”127.0.0.1″; $db = ‘test’; $user=”root”; $pass=””; $charset=”utf8mb4″; $usid = 0; $docname=””; $dsn = “mysql:host=$host;dbname=$db;charset=$charset”; $options = … Read more
[ad_1] Looking at the original code, there are two potential reasons for the NullReferenceException you are getting. First, tb is not defined in the code you provide so I am not sure what that is. Secondly, TextBox textbox = form.Controls[“textboxMain”] as TextBox can return null if the control is not found or is not a … Read more
[ad_1] On some systems keyboard can repeate sending key event when it is pressed so with pynput you would need only this (for key ‘a’) from pynput.keyboard import Listener, KeyCode def get_pressed(event): #print(‘pressed:’, event) if event == KeyCode.from_char(‘a’): print(“hold pressed: a”) with Listener(on_press=get_pressed) as listener: listener.join() But sometimes repeating doesn’t work or it need long … Read more
[ad_1] You just try to convert char* to int. You code should be: int number = atoi(argv[1]) 0 [ad_2] solved c++ Why can’t I use static_cast to convert char* to int?
[ad_1] It’s all about ratio. You need to calculate the ratio between the rectange width & frame width. Sample code here.. function renderBox() { const width = document.getElementById(‘width’).value; const height = document.getElementById(‘height’).value; const box = document.getElementById(‘box’); let scale = 1; while(true) { if (width <= (400 * scale) && height <= (200 * scale)) { … Read more

[ad_1] It seems like you’re trying to set the value in a column called “january” to zero for all rows. Is that really what you want to do? If so then try to remove the quotes around “$date”. It shouldn’t be quoted because it’s a column name. Also, note that if $date would come from … Read more
[ad_1] A user of a stack implementation expects a dynamic data structure. C does not provide that directly in language terms. You have to allocate and administrate the memory your own. Allocating an array, therefore a static sized structure, is very easy. However, you have the problem, that the number of maximum entries is limited. … Read more
