Hello,

	I have the following class:

class SLList
{
public:
  SLList *clone();
  operator=();
private:
  int *value;
}

	clone() creates another instance of the class, containing the same 
value for 'value', but not the same pointer (it allocates new memory.)
Operator=() deletes the old instance and copies the memory location of
the new instance (shares the memory.) My question is... If I say 
'temp=someSLList.clone()'... someSLList.clone() never gets delete()d, 
temp does.. But since temp and someSLList shared the same value, is 
delete()ing temp enough? Will someSLList be left floating somewhere in
memory if I only delete() its variables from another instance? Thank 
you,

Gili
