metod, calculating ages with class Date

[him1979]

If i have a class desribing dates from the calendar and second class Student with members:
name, date of birth(using the first class)

how could i write a method for the second class with parameter date that returns the ages of the student?

My guess:

create a method in the class Calendar that takes the object parameter Student. The method will be looking like:

int Calendar::today(void){
    //Here somehow retrieve today's date, and try to have it in an integer format (like it does in Excel)
}

int Calendar::getAge(student *stu){
     return ((today() - stu->birthdate)/365.25)
    //I'm assuming the birthdate is in the same format as today's date
}

This is not a good guess:

My guess:

create a method in the class Calendar that takes the object parameter Student. The method will be looking like:

The reason is that the Calendar class and the Student are not related. The relationship is the other way: The Student HAS-A Calendar:

[code=cpp]
class Student
{

private:
Calendar birthdate;
public:
int operator-(Calendar& dt);

};
[/code]

You write an operator- method on the Calendar to take the difference between two dates. You call it from your Student class with the birthdate and a date that is today's date.

[code=cpp]
int Student::Age(Ca lendar& dt)
{
return this->birthdate - dt;
}
[/code]
