Study Notes
Polymorphism in C++
-
Keyword for Polymorphism: The
virtual
keyword is used in C++ to implement polymorphism. - Purpose of Virtual Functions: Virtual functions in C++ allow for runtime polymorphism, enabling the correct function to be called based on the object's type, rather than the reference or pointer type.
Virtual Functions
- True Statement: A true statement about virtual functions in C++ is that they can be overridden by derived classes.
- Not a Characteristic of Polymorphism: Polymorphism is not limited to inheritance; it can also be achieved through function overloading and operator overloading.
Disadvantages of Virtual Functions
- Disadvantage: One disadvantage of using virtual functions in C++ is that they can result in slower performance due to the overhead of dynamic dispatch.
