c++11 - Is it possible to auto add some code, when I add class member variables -

i'm boost newbie.

i know possible

when add class member variable(at header file) automatically generate code

// classa.h file class classa {     public:         int a; // in fact a,b,c structure.         int b;         // add "int c;"          void save(); // want auto generate code @ save()         void load(); } 

when add "int c;"

// classa.cpp void classa::save() {     somestream << << b; // use boost::serialize      // want auto replace above code next     // somestream << << b << c; }  void classa::load() {     somestream >> >> b;      // replace above      // somestream >> >> b >> c;     // same order } enter code here 

it possible? using boost mpl? macro?

i have variable add lot.

the closest can std::tuple<int,int> data can grow std::tuple<int,int,int>, see here how print them.
