I have a very simple class State containing a bunch of variables. Now I want to define State State::operator + (State) that simply returns a State object of which the values of the variables are the sum of the same variables, eg:
1 2 3 4 5 6 7
State State::operator + (State b)
result.x = x + b.x;
result.vel = vel + b.vel;
. Now I want this code to be ajustable for other problems, so that ideally I just have to add a variable in the class definition and the operator will automaticly include it in its operation. (Not just because I'm lazy, but also because I want others to be able to use the code without problems, so it should be as straight forward as possible). Can this be done?

Assuming your defintion of operator + continues to mean that each of the variables are added, then yes. e.g If you add a variable y to your class, then certainly you can add result.y = y + b.y; to your operator function.
Thank you, but that's not what I'm looking for. The point is I want to operator to include all variables without me explicitly telling it to do so (ie. an operator that goes through all variables without naming them explicitly).
