Boost.Serialization [1] does this for you. You can serialize into
various wire formats. If you feel comfortable with templates, you can
add your own format (or even Protocol Buffer, although contrary to the
other respondents, I am not a big fan of it). I have added several
formats, including JSON [2].

In you own class, all you need to do is add the serialize() member
function as shown below.

   class Instruction

   template <typename Archive>
   void serialize(Archive& archive, const unsigned int)
      archive & IntData;
      archive & DblData;
      archive & StrData;

   //Data Members
   const unsigned int IntData;
   const double DblData;
   const std::string StrData;
