VS2008 C + + Object memory layout (6): Pointer to member function

VS supports pointers to member functions, which are tested using the class above:

Class Cparenta
{
Public
int parenta_a;
int parenta_b;

Public
virtual void parenta_f1 () {this->parenta_a = 0x10;}
virtual void Parenta_f2 () {this->parenta_a = 0x20;}

Public
void Parenta_f3 () {this->parenta_a = 0x30;}
void Parenta_f4 () {this->parenta_a = 0x40;}
};

Class CPARENTB
{
Public
int parentb_a;
int parentb_b;

Public
virtual void parentb_f1 () {this->parentb_a = 0x50;}
virtual void Parentb_f2 () {this->parentb_a = 0x60;}

Public
void Parentb_f3 () {this->parentb_a = 0x70;}
void Parentb_f4 () {this->parentb_a = 0x80;}
};

Class Cchild:public Cparenta, public cparentb
{
Public
int child_a;
int child_b;

Public: function of//subclass
virtual void child_f1 () {this->child_a = 0x90;}
virtual void Child_f2 () {this->child_a = 0xa0;}

Public://non-overloaded functions
void Child_f3 () {this->child_a = 0xb0;}
void Child_f4 () {this->child_a = 0xc0;}

Public://functions that overload the parent class A
virtual void Parenta_f2 () {this->child_a = 0xd0;}
virtual void parenta_f1 () {this->child_a = 0xe0;}

Public://functions that overload the parent class B
virtual void Parentb_f2 () {this->child_a = 0xf0;}
virtual void parentb_f1 () {this->child_a = 0xFF;}
};


Cchild Child, *pchild;
Cparenta parent, *pparent;
