Answer / monalisha

In C++ an abstract class is one which defines an
interface, but does not necessarily provide implementations
for all its member functions. An abstract class is meant to
be used as the base class from which other classes are
derived. The derived class is expected to provide
implementations for the member functions that are not
implemented in the base class. A derived class that
implements all the missing functionality is called a
concrete class .

The Standard Template Library, or STL, is a C++ library of
container classes, algorithms, and iterators; it provides
many of the basic algorithms and data structures of
computer science. The STL is a generic library, meaning
that its components are heavily parameterized: almost every
component in the STL is a template.

Answer / dumitru

In C++ an abstract class is a class that contain at least
one pure virtual function ( f()=0; ) and is related at using
this only for inheritance, not for instance an object from
this directly.
