Examples of constructor and destructor invocation order in C + + multiple inheritance

Multiple inheritance #include <iostream>using namespace std;class a{public:     A ()     {        cout<< "a base class construction a::a ()" << Endl;    }    ~a ()     {         cout<< "A base class destructor A::~a ()" <<endl;    }};class b:public  a{public:    b ()     {         cout<< "B Subclass construction B:b ()" <<endl;    }    ~b ()      {        cout<< "B-Subclass destructor B:~b ()" <<endl;     }};class c:public a{public:    c ()     {         cout<< "C Subclass construction C::c ()" <<endl;     }    ~C ()     {        cout<< "C Subclass Destruction C::~c ()" << Endl;    }};class d:public b,public c{public:    d ()     {        cout<< "D grandson class structure D::D ()" << Endl;    }    ~d ()     {         cout<< "D grandson Class destructor d::~d ()" <<endl;    }};int main (int  argc, char *argv[]) {    d d;    return 0;}

You can see that the construction order a->b->a->c-d; the destruction order.
