using tuple with class as type C++

Question

I have defined a method for class Rettangolo like this

std::tuple<int, Point, Point> Rettangolo::interseca(Point *sol_p, Point *pvet){
//code
//code
return std::make_tuple(1, *pto1, *pto2); //example of return
//more code
}

My problem is to use the returned values in main. I need to do

(*it)->interseca(sol,normperp);

but basically i don't know how to save and so use the returned values since my tuple type isn't standard

Thanks for your help

When you say that your "tuple type isn't standard", what do you mean by that? What do you consider being a "standard" tuple type? — Some programmer dude, Aug 07 '14 at 08:50

Assign the result of the call to a variable:

std::tuple<int, Point, Point> tpl = (*it)->interseca(sol,normperp);

or

auto tpl = (*it)->interseca(sol,normperp);
