Reading the rest of this thread makes me think you are fundamentally 
confused by C++ library types. In so far as is possible (and we have 
worked hard to ensure that there are few exceptions) a library type such 
as std::string behaves identically to a fundamental type such as int.

int main(){
   double d(0);
   d += 1;
   d += 2;
   d += 3;
   double d1(d);
   std::cout << d1 << std::endl;  // outputs 6
}

Should not cause you to wonder about how the values of d and finally d1 
are stored. Any storage management and conversions from literal values 
will be handled automatically.

And:

int main(){
   std::string s("help");
   s += " me";
   s += " please";
   std::string s1(s);
   std::cout << s1 << std::endl; // outputs 'help me please'
}

Should not cause you to wonder about how the values of s and finally s1 
are stored. Any storage management and conversions from literal values 
will be handled automatically.
