Question 1

What is virtual function

Answer 1

A virtual function is a member function that you expect to be redefined in derived classes. When you refer to a derived class object using a pointer or a reference to the base class, you can call a virtual function for that object and execute the derived class’s version of the function.

Question 2

What is static binding

Answer 2

Static binding means that target function for a call is selected at compile time

Question 3

What is dynamic binding

Answer 3

Dynamic binding means that target function for a call is selected at run time.

Question 4

What is limited polymorphism

Answer 4

When we have base class object/reference and it is pointing to derived class object/reference, so we can call derived class member functions through base class pointer/reference. It is called limited polymorphism.

Question 5

Does C++ apply dynamic binding with virtual functions or we can say polymorphism uses virtual functions for dynamic binding

Answer 5

Yes
