How do I make a class call it's own address

I would like to make a class and have it store it's own memory address as a private data member automatically when it is created. Additionally I would like to make a function within that same class which, when called on, can determine it's memory address and store it in the private date member. Is there a way to do this?

Maybe something like this?

Code:

---

#include <iostream>

class T
{
  T *address;
  void (T::*mypfoo)();
public:
  T() : address(this)
  {
      std::cout << "address = " << address << '\n';
  }
  void foo()
  {
      mypfoo = &T::foo;
  }
};

int main()
{
  T a, b, c;
  a.foo();
  b.foo();
  c.foo();
  return 0;
}

/* my input/output
address = 0012FF88
address = 0012FF84
address = 0012FF80
*/

My understanding is that you just want the memory address of the class instance, not of the member functions. In that case it is already stored (no need for a private variable). The keyword 'this' is a pointer to the current object instance, and you can use it as the address of the instance.

As I understand, C++ simulates reference passing with pointers. When you call member functions of a class, you are essentially calling a global function with the particular instance of the class passed by reference as an argument.

There is also a way to get the addresses of member functions, if that's what you want. (Function pointers.) I think you can only do that outside of the member function, though. However, you can try to create a function object with a constructor (to get its address) and oerloaded operator(), and use a static instance for each class. The syntax might be a little convoluted, so you should have a very good reason for wanting to do this.
