6. Given: class Pet { public: virtual void eat() { cout eat(); } What is the result of compiling and running the above program? m. The program compiles and crashes when it runs. i. The program compiles and runs, printing "Pet::eat" j. The program compiles and runs, printing "Cat::eat" The program compiles and runs to completion without printing anything. n. o. None of the above. k. The program fails to compile because the method eat is not marked virtual in Cat. I. The program fails to compile for some other reason.
