Subject: [sv-bc] Can abstract class be instantiated?


Hi,
As per 1800 LRM (section 7.19, page 93), an abstract class can not be
instantiated.
An abstract class cannot be instantiated; it can only be derived.

But later, in section 7.20, it is mentioned:
Even though BasePacket is abstract, it can still be used to declare a
variable: 
BasePacket packets[100];

What is the difference between an instance of a class and a variable
declaration of class?
