RE: what is virtual function?from where java name came...
Virtual Functions are of two types one is Pure Virtual Function and other is simple Virtual Functions

These functions are mostly used in C++ and C#


Pure Virtual function is

virtual void abc()=0; This will make the class abstract and the object of class cannot be created . and the function must be overwritten in derived class.



Virtual functions are just like normal functions but they are used in Dynamic Polymorphism .

virtual void get()
{


}
