Hi All,

I have a question.

In C#, I have auto garbage collector so I can freely do:

ICar pGenericCar = carFactory.createCar( toyotaEnum );

Without worrying about memory leaks.

in C++, how can I do the same without memory leaks?

ICar pGenericCar = carFactory.createCar( toyotaEnum ); // who will
delete this heap object since C++ interfaces have no ctor or dtor?

Are you speaking about managed or native C++?

In managed C++, the garbage collector will work exactly yhe same as in C#.

In native C++, there is no such thing as an interface, and ICar is therefore
a class or a struct. You can define a destructor on it.
