Hey sup all
I was wondering, what is the point of typedef. I read about it, but I dont understand the point of it.
What so useful about it?

And the other thing was, passing objects as parameters.
...how should u pass objects as parameters, call by value, reference, or constant... or are there situations where each is useful?

I dont think as passing them as constant makes sense, but I read about it in a book which im suppose to be reading from in my class.

Any help or ideas would be appreciated,
thanks!
