-### Data Structures
-A data structure is a group of data elements grouped together under one name. These data elements, known as members, can have different types and different lengths. Data structures can be declared in __AerScript__ using the following syntax:
-
-    struct data {
-        string fname;
-        string lname;
-        int age;
-    } $person1, $person2;
-    struct data $person3;
-
-    $person1.fname = 'Martin';
-    $person1.lname = 'Smith';
-    $person1.age = 27;
-
-    $person2 = {fname => 'Andrew', lname => 'Smith', age => 22};
-    
-Structure members can be access by using a dot operator (.). The arrow operator cannot be used because a structure is not an object.

 ### Exponentiation Operator
 A right associative \** operator can be added to support exponentiation, along with a \**= shorthand assignment operator.
 
     printf("2 ** 3 = %d\n", 2 ** 3); // 8
     printf("2 ** 3 ** 2 = %d\n", 2 ** 3 ** 2); // 512

+        public float $height;
+        public float $length;

+        operator +(Box $box1, Box $box2) {
+            object $box = new Box();
+            $box->breadth = $box1->breadth + $box2->breadth;
+            $box->height = $box1->height + $box2->height;
+            $box->length = $box1->length + $box2->length;
+            return $box;
