Question about defining classes

Hey, I am just wondering if a class definition can include two constructors, such as the following:

Year(int days = 365, int weeks = 52, int months = 12);
Year();

Thanks (my intuition says yes and that the empty constructor would yield random values for the arguments...but my intuition tends to be wrong a lot :))

Code:

---

class Year
{
        Year(int days = 365, int weeks = 52, int months = 12);
        Year();
};


int main()
{
        Year y; // Which constructor?
}

But you may have more than one constructor. You can't just set all defaults like that though.

Ah yep, makes sense. Thanks for the assistance.

Your class can have two (or more) constructors, but not like you posted. Constructors follow the same rules as regular functions in this situation.

Classes can have as many constructors as reasonably required; think std::string

Code:

---

std::string a = 'a';
std::string b = "b";
std::string c = a + b;

---

The main point is to avoid ambiguity. For example, you shouldn't really provide a constructor for each of two objects which easily cast to each other.
