Address - Person

You are given code where the address is integrated into the Person class. This isn't following the single responsibility principle. Separate the class information into two distinct classes: Person and Address. The Person class should have member variables for name and age, and the Address class should have member variables for street, city, state, and zip_code. Demonstrate creating a Person instance and an Address instance, setting their values, and printing them.

#include <iostream>
#include <string>

class Person {
private:
    std::string name;
    int age;
    // Address variables
    std::string street;
    std::string city;
    std::string state;
    std::string zip_code;

public:
    Person(const std::string& name, int age, const std::string& street, const std::string& city, const std::string& state, const std::string& zip_code)
        : name(name), age(age), street(street), city(city), state(state), zip_code(zip_code) {}

    void print_details() const {
        std::cout << "Name: " << name << ", Age: " << age << std::endl;
        std::cout << "Address: " << street << ", " << city << ", " << state << ", " << zip_code << std::endl;
    }
};

int main() {
    Person person("John Doe", 30, "123 Main St", "Springfield", "IL", "62701");
    person.print_details();

    return 0;
}

Hint

Create an Address class with private member variables:
- std::string street
- std::string city
- std::string state
- std::string zip_code
Create a Person class with private member variables:
- std::string name
- int age
- Address address
Implement constructors, getters, and setters for both classes as needed.
Implement a print_details method for both classes to print their information.
In the main function, create instances of Person and Address, set their values, and print their details.

Answer

#include <iostream>
#include <string>

// Address class definition
struct Address {
    std::string street;
    std::string city;
    std::string state;
    std::string zip_code;

    // Constructor
    Address(const std::string& street, const std::string& city, const std::string& state, const std::string& zip_code)
        : street(street), city(city), state(state), zip_code(zip_code) {}

    // Method to print address details
    void print_details() const {
        std::cout << "Address: " << street << ", " << city << ", " << state << ", " << zip_code << std::endl;
    }
};

// Person class definition
class Person {
private:
    std::string name;
    int age;
    Address address;

public:
    // Constructor
    Person(const std::string& name, int age, const Address& address)
        : name(name), age(age), address(address) {}

    // Getters and setters
    std::string get_name() const { return name; }
    void set_name(const std::string& name) { this->name = name; }

    int get_age() const { return age; }
    void set_age(int age) { this->age = age; }

    Address get_address() const { return address; }
    void set_address(const Address& address) { this->address = address; }

    // Method to print person details
    void print_details() const {
        std::cout << "Name: " << name << ", Age: " << age << std::endl;
        address.print_details();
    }
};

int main() {
    // Create an Address instance
    Address address("123 Main St", "Springfield", "IL", "62701");

    // Create a Person instance
    Person person("John Doe", 30, address);

    // Print details
    person.print_details();

    return 0;
}
