Answer / orvaishnavi
The size of an empty class is 1.
Reason - An object of a class should have unique address.
In order for the object to get unique address, the compiler
inserts a dummy type of size 1(least positive value) into
the empty class so the sizeof the class is returned as 1.

Answer / vinay singh
the size of class is nothing until it will not create an object. Class is a template so class object size is determined.So here empty class object size is 1 byte and object is created on managed heap.
