You are working on a graphical app, which includes multiple different shapes. The given code declares a base Shape class with an

abstract area() method and a width attribute. You need to create two Shape subclasses, Square and Circle, which initialize the width attribute using their constructor, and define their area() methods. The area() for the Square class should output the area of the square (the square of the width), while for the Circle, it should output the area of the given circle (PI*width*width). The code in main creates two objects with the given user input and calls the area() methods.
Sample Input:
5
2

Sample Output:
25
12.566370614359172

The area of the square is 5*5=25, while the area of the circle is PI*2*2=12.566370614359172

A friend has a CD of one of your favorite artists and has offered to let you copy it.
creativ13 [48]
No; copyright laws protect this artist's rights and I need to purchase the CD if I want it.  

This is due to copyrights being applied at the time of fixation.  In other words, as soon as the words or lyrics have been placed on paper, recorded or put in a computer the ARTIST is protected.
