Polymorphic Array of Shapes

The abstract base class Shape declares a pure virtual area(). Complete BOTH derived classes:
- Square stores a side and its area() returns side times side
- Rectangle stores width and height and its area() returns width times height

The provided main stores both kinds in an array of Shape pointers and prints the total area — the correct area() is chosen for each object at runtime.

Expected Output:

29↵

= newline. The output ends with a newline — print one after the last line.
