9.18.2.Call base's constructor and destructor from derived class

#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; 

}
