Answer / kiran

1 We must say a class as abstract if it contains at least
one abstract method
2.you cannot create instance of an abstract class.

Answer / umesh

A class that cannot be instantiated. A concept in C++ known
as pure virtual method. A class that must be inherited and
have the methods over-ridden. Essentially, it?s a blueprint
for a class without any implementation.

Answer / mohit

it is not pure virtual class like interface. in this we can
implement also method but we can not create instance of
absract class.

Answer / rajesh

I Think they have no meaning,abstact class is nothing but
we are going to use that class in the program(we are
overcoming this class in the main program) and how it looks
like is written at the starting which we call it as
abstarct class.It will not occupy any memory unless we
create object.

Answer / pushparaj pentakota(anakapalli

the class which is having atleast one abstract method is called abstract class.and we can't create an object on these classes.we have to implement those methods in child class to make that as concreate class.
