what's the difference between abstract class and concreate
class? what's the meaning of standard template library(STL)?
Answer Posted / a.srinivas rao
An abstract class is a class which contains atleast one
abstract method(i.e., an abstract method is one which has
only definition not implementation,which is done in some
other class.
We cannot create an object for Abstract class.
A class is said to be a concrete class if and only if it
contains fully defined methods.Defined methods are also
known has "concrete methods " or "Implemented methods".
We can instantiate an object for concrete class.
