[Solved] swift properties setter not getting called

by

It looks to me like area is a computed property. Shouldn’t it be a read-only computed property? Seems to me that there are multiple triangles with a given area but different height/base values, so you can’t set the area in a meaningful way. var area: Double { get { // getter return 0.5 * base … Read more

[Solved] JS comparing innerHTML

by

let pick1 = openCard; You redeclare pick1 inside the function. This creates a new variable that masks the global variable of the same name. Each time you run the function, you get a new pick1 and a new pick2, both of which are undefined. Consequently, you’ll always hit the first half of the if/else. Remove … Read more

mShowAnswers.setText( marksObtained ); This line contains the bug.

[Solved] Uncaught type error is not a function [closed]

Example: document.addEventListener(“DOMContentLoaded”, function(){ // ADD CODE }); Your JavaScript should be working when included correctly as seen in here: function showdivs() { var yourUl = document.getElementById(“tryok”); yourUl.style.display = yourUl.style.display === ‘none’ ? ” : ‘none’; var … Read more

[Solved] Create a list for each item in another list

by

I wouldn’t recommend this course of action. You will probably get all kind of replies telling how you can do this using setattr and friends, but in practice dynamically-created variable names are almost invariably (see what I did there?) a bad idea.

[Solved] Shooting. Collision of the shot with a collection of List

by

Without claiming to rework your design, I added collection of dead invaders(ArmyOfInvaders.deadInvader) to stored those ones, who already shot, and changed InvaderGotShot and DrawItem methods. I got rid of Invader.invader collection and introduced local variable in Invader.InitializeInvader instead of it to prevent misassigning. Please take a look: class Program { static void Main() { Settings.ScreenSettings(); … Read more

vector<int> output_list(n * m); initializes output_list to be size n*m and fills with 0’s. You then push_back values after that. You have 3 options: Don’t initialize output_list to have values. Let the program reserve space on the fly as you push_back. Don’t initialize output_list to have values, but increase its capacity using reserve. Initialize output_list … Read more
