// This program illustrates the need of having a default constructor.
// As you have some constructors for Geometric, the system will not generate 
// any default constructors for you. Now, if non of your constructors 
// is a default one, the system may create a compilation error whenever 
// a need for this default constructor is encountered, or in other cases,
// the program may behave unexpectedly. 

// Key Points: 		1) Default Constructors.
