LAB: Book information (overriding member functions)Given main() and a base Book class, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a PrintInfo() function that overrides the Book class' PrintInfo() function by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes.Ex.
