Convert "this" pointer to string

Question

In a system where registered objects must have unique names, I want to use/include the object's this pointer in the name. I want the simplest way to create ??? where:

std::string name = ???(this);

Answer 1

You could use string representation of the address:

#include <sstream> //for std::stringstream 
#include <string>  //for std::string

const void * address = static_cast<const void*>(this);
std::stringstream ss;
ss << address;  
std::string name = ss.str(); 

Answer 2

You mean format the pointer itself as a string?

std::ostringstream address;
address << (void const *)this;
std:string name = address.str();

Or ... yes, all the other equivalent answers in the time it took me to type this!

Answer 3

#include <sstream>
#include <iostream>
struct T
{
    T()
    {
        std::ostringstream oss;
        oss << (void*)this;
        std::string s(oss.str());

        std::cout << s << std::endl;
    }
};

int main()
{
    T t;
}
