Hi Sujay, As you have mentioned the sizeof() operator for an empty class returns 1
byte.This is because every object you create should be created in a new address
space.Hence addresses of two different objects are different and "new" always returns
pointers to distinct objects. ex: class Empty { }; void main() { Empty
Obj1,Obj2; Empty* ptr1 = new Empty; Empty* ptr2 = new Empty; } //Here
Obj1,Obj2,ptr1,ptr2 are all created in a different address space.Hence it should have
some size and the minimum possible size is 1.Hence the answer. But when you
declare class member variables,the sizeof() an object of such a class would be the sum
of the size's of all the class member variables. This is one of the favorite
interview questions on C++ :).... Regards, Ramesh
