pure virtual function

subject fact

pure virtual function is a C++ abstract operation 2001-08-30 14:57:11.0
is a subtopic of 2.6 - The Effect of Inheritance Hierarchies on Polymorphism and Variable Declarations
is a kind of operation

operation carries out a responsibility of a class 2001-08-30 14:56:53.0
is implemented as a set of methods
is used to discuss and specify a type of behaviour, independently of any code which implements that behaviour

procedural abstraction has advantage when using a certain procedure, a programmer does not need to worry about all the details of how it performs its computations; he or she only needs to know how to call it and what it computes 2001-08-30 14:57:04.0
hides the details of procedures
