Of course a C-style array in C++ doesn't have a defined end. It doesn't have an end in C either. But in C++ you don't need to be using those anyway.

Part of the issue is that, while you can use the usual C idioms in C++ (e.g. a function takes an array and its length as arguments), you don't need to, especially if you're using C++ correctly. This is one of the points of the article.

Like hellofunk said, this has nothing to do with the type system. But the solution to what you're talking about is fundamental C++: use the standard library.
