Instructions
In this exercise, you will be simulating a windowing based computer system. You will create some windows that can be moved and resized. The following image is representative of the values you will be working with below.

╚════════════════════════════════════════════════════════════╝1. Define the properties of the Program Window
Using the provided class scaffold, provide the properties for the y, x, height, and width values.
<?php
$window = new ProgramWindow();
$window->y; // => null
$window->x; // => null
$window->height; // => null
$window->width; // => null2. Define the initial values for the program window
Define a constructor function for ProgramWindow.
It should not take any arguments, but during the constructor execution set the default values for its properties.
It should set the initial y and x values to 0.
It should set the initial height and width to a 600x800 screen size.
<?php
$window = new ProgramWindow();
$window->y; // => 0
$window->x; // => 0
$window->height; // => 600
$window->width; // => 8003. Define a function to resize the window
Define a new class in Size.php for a Size class.
It should take constructor arguments to set the height and width properties.
Additionally ProgramWindow requires a resize function, which receives the Size object instance and updates its own properties.
<?php
$window = new ProgramWindow();
$size = new Size(764, 1080);
$window->resize($size)
$window->height;
// => 764
$window->width;
// => 10804. Define a function to move the window
Define a new class in Position.php for a Position class.
It should take constructor arguments to set the y and x properties.
Additionally ProgramWindow requires a move function, which receives the Position object instance and updates its own properties.
<?php
$window = new ProgramWindow();
$position = new Position(80, 313);
$window->move($position)
$window->y;
// => 80
$window->x;
// => 313Windowing System
