structure is a value type class is reference type,
struct Memory will be on stack and class Memory stored on 
Heap,
struct not suports inheritance and class can?

By default the members of struct are public.
By default the members of class  are priavte.

When an object is created to a class, constructor will be 
called automatically.
But not in struct (if structure having member function with 
structure name)

class is a slow access because of heap memory. But struct 
is a faster in access because of stack  memory.



values are initialize at the time of declaration in class
but not in struct.
