Hey there. Posting from mobile and I got my post eaten due to timeout 3 times no so I'm reaching the end of my patience. Also I can't access out of pod so I'm sorry in advance for posting this here. I got a quick question and I'm grateful for any help anyone might offer regarding my issue:

I need to create a class that takes the parameters length and width and after doing so it finds out whether it's a square or not.

If it is, it then calculates its area/surface (length * width). And there seems to be a trick regarding the parameters but I can't seem to figure it out.

Any help would be greatly appreciated. Thank you for the help and/or good troll attempts.


STUPID FORUM TIMEOUT. FIX THE POST EATING ISSUE PLEASE!!!

Ok I get the part where it grabs the sides and calculates the area but 2 questions:

1. what's the deal with that 15 there. Did you mean 25 which would be the result of 5 *5?

2. Is there any piece of code there that actually checks if the sides are equal (aka being a square?) or any other way of determining the shape of the object?

I suspect the numbers used are hard-coded for readability. (Any programmer will tell you) NEVER to hard-code numeric values. Always pass or declare predefined vars. (EDIT unless they are constants like Pi/SoL etc.)

I can't answer Q2 without knowing what vars are available. If I can assume W and L, then it's a simple if {} construct to determine if it's a square.

I'm rusty on PHP so any other assist from other forum members would be good.

It reminds me of when I use to lecture in programming. I always gave my phone number to students to contact me if they got stuck on assignments.

Had a call at 3.00am from a student saying he was stuck on Question x.

I was pretty nasty reminding him what time it was.

His reply. "You set the deadline!".

I failed him.

class rect {
private $w;
private $l;
function __construct($length, $width) { $this->l = (int) $length; $this->w = (int) $width; }
function isSquare() { $this->w === $this->l ? return $this->w*$this->l : return FALSE; }
}

…or some such. I just realised I haven't touched PHP in years, so I'm sure it'll break something. Oops

  class SquareThingy{
    private $length;
    private $width;
    
    function __construct($length, $width){
      $this->length = $length;
      $this->width = $width;
    }
    
    // Call this to check if the object is a square
    function IsSquare(){
      if ($this->length == $this->width) return true;
      else return false;
    }
    
    // Call this to get the area
    function GetArea(){
      return $this->length * $this->square;
    }
  }


How to use this?

Construct the object
$object = new SquareThingy(4, 8); // 4 is length, 8 is the width

$object->IsSquare() // Gives true or false

$object->GetArea() // Gives the area

You're not alone. I am usually pretty specific with deadlines, saying "Jan 15th 23:59", so there's no confusion. Every single time I get three submissions between 23:00 and midnight, often at least one after 23:55.

What all you failed at is providing proper set methods for the arguments in the constructor.

I <3 the eve forums. Nowhere else would you get this sort of response on a game communities main board.
