Constructor & Destructor

Your code doesn't make sense: you cannot have parenthesis after a class declaration class a().

Well your code won't compile so the question is a bit moot. To get your code to compile you'd have to rewrite it along the lines of the following:

class a
{
    a();
    ~a();
};

class b
{
    b();
    ~b();
};

Unfortunately it won't actually do anything at this point - all you've done is describe a pair of classes to the compiler and not actually told it to do anything.

However as soon as you actually try and create objects of type a or b the compiler will complain that the constructors for the objects are private and it can't create objects of those types.

When you fix that you'll probably find the linker complaining that it can't find definitions of a::a(), a::~a(), b::b() and b::~b(). By the time you fix that lot you'll have a program that you can probably execute AND find out the answers to what you want to know.

are you sure, you looking for this

class a
{
    a();
    ~a();
};

class b
{
    b();
    ~b();
};

as I doubt you might be looking for this:->

class a
{
    a();
    virtual ~a();
};

class b: public a
{
    b();
 virtual ~b();
};

In above case, A constructor will be called, then B constructor will be called.

and at the time of destroying the B destructor will be called then A.

there is just a declaration, and no executive code, like objects creation, etc. so there will be no sequence
