Destructors and containership

[rajapratap]

Hi there,
I would like to know if I can call the destuctor explicitly in case of
containership.

Lets consider an example:
class A
{
public:
~A()
{
cout <<"~A()"<<endl;
}
};

class B
{
A a;
public:
~B()
{
cout << "~B()" << endl;
//a.~A()
//please pay extra concentratio here..
}
};


In the above case the destructor of A should be called explictly or not? If I dont call, the destructor for A is never called.

Thanks in advance,
Pratap Reddy

You never need to explicitly call a destructor. Even if you define your own destructor in class B when you destroy class B it will call the destructor on any member objects as well (ie. the member object "a" will also be destroyed).
