Hi,

Anyone can tell me the difference between an abstract base class and
an interface?

Thanks!

The most obvious differences are:

1) You can implement multiple interfaces, but only derive (directly)
from one base class
2) Abstract classes can have implementations - interfaces *just*
specify what the members of the interface are, not how they're
implemented
