Answer / subhashish sen
Constructor can't be virtual,becoz constructor is an entity
which initializes V-table(V-table contains addrress of all
the virtual functions of class).So if we declare constructor
as virtual the who will intialize V-table for this constructor.
Destructor can not be overloaded simply becoz we cant
provide argument to a destructor and also its going to
release the memory when an object goes out of scope.

Can we create object of interface?
class CTest { public: void someMethod() { int nCount = 0; cout << "This is some method --> " << nCount; } }; int main() { CTest *pctest; pctest->someMethod(); return 0; } It will executes the someMethod() and displays the value too. how is it possible with our creating memory for the class . i think iam not creating object for the class. Thanks in Advance... Prakash
