I downloaded that book thinking knowing some C++ couldn't hurt. It might even make me a better programmer. Etc.
Then I see code like
template<class T> class Ptr { public:
// new member to copy the object conditionally when needed
void make_unique() {
if (*refptr != 1) {
--*refptr;
refptr = new size_t(1);
p = p ? p->clone() : 0;
}
}
// the rest of the class looks like Ref_handle except for its name
Ptr(): refptr(new size_t(l)), p(0) { }
Ptr(T* t): refptr(new size_t(l)), p(t) { }
Ptr(const Ptr& h): refptr(h.refptr), p(h.p) { ++*refptr; }
Ptr& operator=(const Ptr&) ; // implemented analogously to §14.2/261
~Ptr(); // implemented analogously to §14.2/262
operator bool() const { return p; }
T& operator*() const;, // implemented analogously to §14.2/261
T* operator->() const; // implemented analogously to §14.2/261
private:
T* p;
size_t* refptr;
};
MY FUCKING EYES FUCKING HURT BECAUSE THIS FUCKING CODE IS FUCKING TERRIBLE.
THIS CODE IS SO TERRIBLE THAT COULD ACTUALLY WIN AT THE UNDERHANDED C CONTEST.

p=(p=p?p=p:0);
LOOK HOW COOL MY CODE LOOKS LIK

I really don't see what's so bad about the block of code in >>7. The only thing I find stylistically unappealing is putting the public: right after the opening brace.
All the actual code is straightforward and pretty simplistic. Good example code.
It's a very straightforward reference counted pointer. It's not like the average dev ever really needs to write this sort of thing, that's what Boost is for, but this block is neither complicated nor particularly difficult to understand. Hell, there are only 5 lines of actual code! The rest is just boring, humdrum plumbing

If you're going to be a pussy about programming in C++, at least be a pussy about stuff that's interesting.
Oh lawd. Stay far away from this book if you're a newb. It'll only scare you, and you'll never come back. It's a good book for reference, or improving skills if you already know the basics, but learning from that is a bad bad idea. There are many other texts out there that are just as good, as far as content goes, but more newbie friendly.
