#include <iostream>
using namespace std;

class BaseClass {
public:
BaseClass() { cout << "Constructing base portion\n"; }
~BaseClass() { cout << "Destructing base portion\n"; }
};

class DerivedClass: public BaseClass {
public:
DerivedClass() { cout << "Constructing derived portion\n"; }
~DerivedClass() { cout << "Destructing derived portion\n"; }
};

int main()
{
DerivedClass ob;

// do nothing but construct and destruct ob

return 0;
}

output will be :-----------
Constructing base portion
Constructing derived
Destructing base portion
Destructing derived
