                 You will get the following output:

                 Do you want more : y
                 Object Number : 2
                 Do you want more : y
                 Object Number : 3
                 Do you want more : y
                 Object Number : 4
                 Do you want more : n


                 14.3.3 Instance Variables
                 They are also known as non-static data members. They are created whenever any object is generated. Every instance
                 variable is accessed by preceding it with the object name. They are declared in a class, but outside a method, i.e., both
                 constructor and user-defined method. A distinct copy of the variables is be created for each object of the class.
