When is it good idea to calculate an object's attribute on the fly rather than storing it as a data member?

The only time you should calculate it instead of storing is when you only use that attribute once. Otherwise, store it to avoid repeating calculations.

How do you call 2 or more objects in c plus plus?
It's not clear what you mean by "call 2 or more objects". Object's aren't "called", they are instantiated. Once instantiated you may "call" (invoke) the member methods associated with those objects, or invoke functions that operate upon those objects. To invoke the same member method on 2 or more objects, simply place those objects in a vector (by reference), then iterate over the vector: void f (std::vector<my_object*> objects) { for (auto foo : objects) foo->bar(); // invoke the bar method for each foo object in objects }
