Make a class diagram of your Design. Code: The code is as follows. Date.h #define DATE_H #include <string> using namespace std; class Date{ public: std::string depart_date; std::string arrival_date; Date() { depart_date = "12-03"; arrival_date = "12-03"; } void setDepartureDate(string d) { depart_date = d; } std::string getDepartureDate() { return depart_date; } void setArrivalDate(string a) { arrival_date = a; } std::string getArrivalDate() { return arrival_date; } }; Time.h #define TIME_H class Time{ public: int depart_h, depart_m; float arrival_h, arrival_m; Time() { depart_h = 12; depart_m = 20; arrival_h = 2; arrival_m = 50; } void setDepartureHour(int dh) { depart_h = dh; } int getDepartureHour() { return depart_h; } void setDepartureMin(int dm) { depart_m = dm; }…
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.

Modify and rewrite the Food class to an abstract class, so that no instance of Food class can be created
Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…
