14. Assume that class B is derived publicly from class A. Class A has two functions, f10 and f20). Function f20 is virtual. Assume the following statements statements: A* ptr=new B; ptr->f10; ptr->f20; Fill in the blank. The function f1() as defined in class will be used. The function f20 as defined in class — will be used. 15. In question 14, the call to ptr->f2() is an example of 16. A virtual function that has no definition and is set to zero is said to be a.
