Does C++ offer mated constructor / destructor combos?

Is there something like this:
class CWhatever
{
public:
// Mated constructor / destructor pair
CWhatever(... params ...)
{
// Constructor code here
std::cout << "Constructor" << std::endl;
} ~ {
// Mated destructor code here
std::cout << "Mated destructor" << std::endl;
}
// Generic destructor
~CWhatever()
{
// Generic destructor code here
std::cout << "Generic destructor" << std::endl;
}
// Other things here
};
Such that it would generate this output on use:
Constructor
Mated destructor
Generic destructor

There is only ever one destructor. If the work of the destructor
depends on how the object was construct, include a flag. This pattern
is uncommon.
