Consider the following code fragment: class Animal { public: void Eats() { cout < < "Eats food." < < endl; } }; class Lion public Animal { public: Lion() Animal(), m_name("Leo") {} Lion(string name): Animal(), m_name(name) {} void Eats() { cout < < m_name < < " eats meat." < < endl; } void Sleep() { cout < < "Ahh...a nice nap!" < < endl; } private: }; string m_name; a. Suppose leo is a Lion object. What syntax would I use to invoke the Eats () method on leo? b. Suppose lionPtr is a pointer to a Lion object. What syntax would I use to invoke the Sleep () method on the Lion object pointed to by lionPtr?
