Destructor should be define.

Destructor has to destroy the object. Thus we have to define destructor inside the main function.

In this program we should also define the destructor, like as,
~Bix()
{ }
It should be like that...we can't not left destructor without defining it :).
~Bix()
{ }
It should be like that...we can't not left destructor without defining it :).

void show() should be declared before destructor.

If destructor cannot be declared, it must be defined within class.

The destructor is not provided the definition.

The destructor is only declared, but not defined anywhere
i.e, it is given like this "Bix::~Bix()" and left without definition.

Kindly note that it's not due to inaccessibility of x. it is very well accessible in Bix::<<anything>> . The destructor is only declared, but not defined anywhere. Hence the compiler throws " undefined reference to Bix::~Bix()" when it's called after the return statement of main().

Here x is declared as private so we cannot access x in main function.
