    Arguments question

    Hallo,

    I have a question about aruments.

    One of my classes takes a Vector3D as an argument (3 floats), which is fine in some cases, but I have to do like this

    Vector3D pos(0,0,10);
    sphere.setPos(pos);

    Sometimes it wuld be nice to be able to do:
    Sphere.setPos(0,0,10)

    Is there a way so that I can switch between the two ways?

    thanks

    Well, if you did not actually need pos, you could write:
    Code:
    sphere.setPos(Vector3D(0, 0, 10));
    Alternatively, if you are able to change the class of the sphere object, you could overload its setPos() member function.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
