C++ | Virtual Functions | Question 1

Virtual functions are functions that can be overridden in derived class with the same signature.

Virtual functions enable run-time polymorphism in a inheritance hierarchy.

If a function is \'virtual\' in the base class, the most-derived class\'s implementation of the function is called according to the actual type of the object referred to, regardless of the declared type of the pointer or reference. In non-virtual functions, the functions are called according to the type of reference or pointer.
