/*Write a  C++ or Java application that creates a linked list of Circle objects/structures (i.e., class must be created).
The application can use the "IntSLLNode" and "IntSLList" classes (pp. 78 - 83) as a guide.
The application must provide the following features.

Allow insertion of  multiple "Circle" objects/structures.
The Circle contains a "radius" data member.
The Circle also uses functions/methods "setRadius", "getRadius" and calculateArea (returns a double data type).
Invoke a method/function "DisplayAllElements" (i.e., must be written, traversal required; refer to "isInList" method, pg. 80) that receives
a "reference/pointer" formal parameter.  This formal parameter specifies the "head" of the list.
The function/method must display all elements "position", "radius" , and "area"
