Overloaded cast?

Hello,
Is there a way to overload the way my class is casted to another object? For example, this is my class:

Code:

---

class CClass1
{
public:
  Class1(int num) { i = num; }
  blah blah

private:
    int i;
};

CClass1 c (5);
int casted = (int)c;

---

So in that case, i would want the 'casted' to have the value of the integer member in CClass1. Is it possible in c++?
Thanks

I think you do something like this, I may be wrong:

Code:

---

class CClass1
{
public:
    Class1(int num) { i = num; }
    operator int()
    {
        return i;
    }

private:
    int i;
};

CClass1 c (5);
int casted = (int)c;
