Fully disagree. Understanding pointer semantics is a pre-requisite for understanding RAII.

  I know C++ since 1993, I am quite curious how pointer semantics have anything to do with RAII.
  • ncmncm 5y ago
    Yeah, doesn't make sense. Pointers are less useful in C++, because we have better things now.
    • junon 5y ago
      Of course we do. You still need to know how pointers work to use RAII effectively, though.
      • pjmlp 5y ago
        Not at all, because RAII is about constructors/destructors, and not at all about pointers. Heap allocated data is one special case of OS resources that can be managed by constructor/destructor pairs.

          What did being pedantic prove here?
          • ncmncm 5y ago
            The thread started with you insisting a C-level conception of pointers is essential to coding C++, which turns out to be false. Learning C first is a very bad way to learn C++. One can pick up pointers later, and asm blocks after that.

    Because smart pointers are still pointers under the hood. You're forgetting the time before you know what pointers were - people coming from higher level languages don't immediately grok the concept. By teaching them automatic memory management patterns like we use in C++ without teaching them why you need such things, they'll never fully understand the code they're writing. It's like the "I know React but not JavaScript" crowd all over again.

      If you think RAII is about smart pointers, you really don't understand it. RAII is about resource management, regardless of where those resources live on. Heap allocated, OS handles, indexes on a fixed sized buffer, network sockets, ...

        Yes, I'm aware, thanks. Lifetimes, ownership, etc. are all overlaps of RAII and associated concepts. Again, what did being pedantic prove here? You clearly understood what I meant.
