Yes C/C++ are pretty weakly typed and Null pointers are an issue in them all. They still catch some issues though and I find it does help me sometimes compared with Ruby for example. If they only caught 2% of the issues I would be a little surprised but it is certainly in the range of possibilities depending on the stage of development (I think it would catch more as you type your code but possibly 2% or less when evaluating a finished, debugged tested product). You can also add Swift to the list of languages that get it right in this regard. When receiving a return value from obj-c that can be null it comes back as an optional so you SHOULD safely transform it to a real value or only perform conditional actions on it. Of course there is the possibility to coerce it into the full type.
