#include <iostream>

class Person

    string _name;
    int _age;


public:


    Person()
    {
        _name = "";
        _age = 0;
    }


    Person(string name, int age = 20)
    {
        _name = name;
        _age = age;
    }


    string GetName()
    {
        return _name;
    }


    int GetAge()
    {
        return _age;
    }
};




int main()
{
    Person defaultConstructor;
    Person defaultAge("Jim");
    Person initializedConstructor("Andrew", 25);
    cout << "Info about person created with default constructor: name = " << defaultConstructor.GetName() << ", age = " << defaultConstructor.GetAge() << endl;
    cout << "Info about person created with default age: name = " << defaultAge.GetName() << ", age = " << defaultAge.GetAge() << endl;
    cout << "Info about person created with initialized constructor: name = " << initializedConstructor.GetName() << ", age = " << initializedConstructor.GetAge() << endl;
    return 0;
}
