{

cout<<"constructor. "<<endl;

}

void destroy()

{

delete this;

}

int main()

{

HeapOnly *p = new HeapOnly;

p->destroy();

HeapOnly h;

h.Output();



return 0;

}



#include <iostream>

}

~StackOnly()

{

cout<<"destructor." <<endl;

void *operator new (size_t);

};


int main()

StackOnly s; //okay

StackOnly *p = new StackOnly; //wrong
