Question

Why is the notion of virtual functions considered to be important for reusability?

a.

Because virtual functions can be redefined by specializations

b.

Because virtual functions cannot be redefined by specializations

c.

Because virtual functions provide a default implementation

d.

Because virtual functions provide a unique implementation

Posted under Software Engineering

Answer: (a).Because virtual functions can be redefined by specializations Explanation:The notion of virtual functions is considered important for reusability because it allows a variant of some object to be created by constructing a specialization of that object, in which some services are redefined. The virtual functions are services of an object that have a default implementation, which can be redefined by specializations of the object, providing greater flexibility and adaptability to different situations.
