多级继承C ++

Question

Suppose a class C inherits from a class B which overrides a virtual function defined in A. C does not override the function. When a pointer of type A* points to an object of type C, will the function call use the overridden version in B?

Answer 1

Yes!

Semantically, C inherits its implementation from B implicitly.
Concretely, the implementation of a virtual function that's called is the most derived available one.

Answer 2

When a pointer of type A* points to an object of type C, will the function call use the overridden version in B?

Yes.

Answer 3

是的函数调用将使用B中的重写版本，除非您在C中实现虚函数。在这种情况下，函数调用将是C.
