/* Question 1 : What is the difference between a class and a structure?
   Answer   1 : Differences between class and structure are as follows:
               1. Classes are of reference types while structures are of value types.
               2. A Class can inherit from another class whereas a structure cannot.
               3. A Class supports 'polymorphism' where as structure does not.
               4. Data members in classes are by default private whereas data members in structures are by default public.
               5. Class has limitless features whereas structures have limited features.
               6. Class is generally used in large program whereas struct is generally used in small programs.
           
*/
/* Question 2 :  When would you want to use one versus the other?
   Answer   2: When a user wants more freedom in terms of what he wants to do, class is the best option as it has limitless features whereas if the user wants a quicker 
               and easier program without having to worry about polymorphism or inheritance structure is the best option.
