The code is the code, and it doesn't magically change because you invoked one overload vs. another. jb4 "So don't pay attention to the approval ratings that say 68% of Americans disapprove of the job this man is doing.

Post #265,060 by tuberculosis 8/16/06 11:48:14 AM Reply	And you specify that by.... the type of the reference to the object. Which can change. Which kind of makes it the anti-polymorphism. But I think Scott is right. 'nuff said.

Post #265,080 by tuberculosis 8/16/06 1:27:58 PM Reply	I wasn't trying to be sarcastic But I know of no allegedly OO language where the method implementation lookup depends on the type of the reference you hold. It runs counter to how polymorphism is supposed to work in which the object responds based on the type of the object and not the type of the reference. So in that respect, C++ is just weird in OO world (and thus, counterintuitive). Gotta warn the newbies.

There is no difference between having a const reference to an object in C++ and having a const object. jb4 "So don't pay attention to the approval ratings that say 68% of Americans disapprove of the job this man is doing.
