Question

I want to allow my Class1 to be convertible to Class2 by a type conversion operator:

class  Class1     {
public:
    operator Class2() const {
      //....
    }
}

But if I create a Class2 object in the operator implementation, very likely it will not get deleted by the caller. So what is the best way to implement such a feature?

Answer 1

There only needs to be deletion if you do something crazy like this:

operator Class2() const
{
    Class2 *p = new Class2();
    ...
    return *p;
}

However, the following is fine:

operator Class2() const
{
    Class2 c2;
    ...
    return c2;
}
