You should always keep your destructors virtual when u r dealing with Inheritance. Try this Code :

Code
#include <iostream>
#include <tchar.h>
 
using namespace std;
 
class Parent
{
public:
        virtual ~Parent()
        {
                cout << " Destroying Parent 
";
        }
};
 
class Child : public Parent
{
public:
        ~Child()
        {
                cout << " Destroying Child 
";
        }
};
 
 
int _tmain(int argc, _TCHAR* argv[])
{
        Parent * abc = new Child();
        delete (abc);
 
        return 0;
}
 

Also try the same code without using virtual keyword before ~Parent() u will see the difference... :)

Virtual destructor is used to delete the dynamically allocated memory via a base class ptr.
