Seems to me a lot of the instructors are basically teaching C using a C++ compiler. You can't use C++ without understanding pointers and C style strings, but the language has evolved over the last 20 years. From what we see here, I'd conclude that a lot of instructors are stuck in the past.

It would make more sense to teach the build in list, vector, set, string, etc classes than to teach how to do it in C at least for beginners. Sure, it's helpful to know how a list or set is implemented, but not right of the bat.

If posts seem arrogant, it's not directed at the poster. It's directed at the instructors who are still teaching the language as it existed in two decades ago.
