Even If I do :
void *p;
p=(void *)s;
delete(p)    EQUAL TO delete(s)  ??
 
So delete doesn't need to know the type of pointer to free memory !
Great!

Another question :
Do delete call the destructor when is argument is a pointer to a class ?

I'm not sure but it seem when you call a destructor you need to makeout
the class type like this ' s->son::~son() ' . So If I don't know the
class type (here son) it's not possible ! Don't you ?

Thank for your help
