How can I complete the implementation of a Person class.

#ifndef PERSON_H

#define PERSON_H

#include

#include

#include "Address.h"

#include "Date.h

using namespace std;

// interface of Person class (what will be the header file) class Person { public: // member functions // constructors Person(); // default constructor - no name, address, DOB, phone Person(string ); // just a name nothing else Person(string, Address ); Person(string, Address, Date ); Person(string, Address, Date, string ); // mutators - setters void set_name(string ); void set_address(Address ); void set_dob(Date ); void set_phone(string ); void read(); void read(ifstream& ); // accessors - getters string get_name() const; Address get_address() const; Date get_dob() const; string get_phone() const; int get_age() const; void display() const; void print(ofstream& ) const; private: // data members string name; Address addr; Date dob; string phone; };

#endif

Also, add the following member functions to Address. #ifndef ADDRESS_H #define ADDRESS_H #include #include using namespace std; // interface of Address class (what will be the header file) class Address { public: // member functions // constructors Address(); // default constructor Address(int, string, string, string, int ); // mutators - setters void read(); void read(ifstream& ); void change_address(Address ); // accessors - getters void display() const; void print(ofstream& ) const; bool equals(const Address& ) const; private: // data members int street_number; string street_name; string town; string city; int zip_code; }; #endif The driver program should test all member functions in Person and the newly added member functions to Address as well.
