OOP and the scope of a class, am I wrong?
-
My take: A class should group related data and actions that center around a single concept. A car class might contain 4 Tire class instances as data members, an Engine instance, and a Gearbox instance. Each one has actions relevant to its operation like Engine.Start(), and Wheel.Rotate() But I'm hearing that professors are teaching that classes are effectively a single action like

More than thirty years ago, when OO concepts made were first thought of, everyone jumped onto this, and started talking about OO, without really understanding it; much like [The Emperor's New Clothes - Wikipedia](https://en.wikipedia.org/wiki/The\_Emperor's\_New\_Clothes) Everyone could see the 'clothes' the Emperor was wearing, and talk about their grandeur, but the reality was different. History is said to repeat itself, perhaps in the form of these OO professors of today.

OOP? Hell, I'm pissed they never taught anything about debugging techniques or using a debugger! It would make teaching the languages and code much easier if they could see exactly what's changing while the code is running.

They also didn't teach building/making complex software systems. We learned on OpenVMS and the debugger is nigh on unusable so it's no surprise they didn't teach it. Learning how to debug without a debugger is much more important anyway.

The prof is teaching “microServices” I remember seeing a text book purporting to teach OO with C++. I seriously think that a professor took an Introduction to Programming with classic BASIC and converted it paragraph by paragraph to C++. It was horrendous!

I wish they would have taught just the basic technique of outputting suspect variables to the console, but when I was going, they didn't teach even that.

When I was learning C++, most college professors knew a bit of C and taught C as C++. I see things have not improved

I believe ablative gerund belongs to latin grammar, and there is no such thing as easy latin. But I'm probably wrong though, as I never learned latin.

No, not at all. A class, in the various languages that contemplate it as a construct, is one of several possible forms of implementing an ADT (Abstract Data Type). Generally data + code, plus some other "automation" to implement inheritance and, consequently, dynamic polymorphism, at least in languages like C++. An ADT is also an opaque structure (like FILE in the C library) in addition to the free functions that operate on it: it does not matter what the "guts/bowels" (hidden part) of a class or structure look like, what matters is the interface with which it allows you to operate, i.e., the functions that accept an explicit or implicit "this".

Your description is very accurate IMHO... Can you - secretly - share the name of the places those professors teaching? I want to ensure my kids don't go near there... :-D

Awesome rabbit-hole :)

Holy ... Dear Richard, you know me now for a longer time as an English non native. Can you please describe 'ablative gerund' in _very simple words_ for me? Thank you very much in advance ;)

Yes - you misspelled "tyre". ;P

Ha ha! I remember "ablative" and "gerund" from my Latin classes back in the 1950s. So I just put the two words together as a joke. But the joke, it appears, is on me, as there realy is such a thing. But I am not sure exactly what that thing is.

You're probably safe. I ran into this while helping a student from South Africa

Not at all. It had ParsePatientData, and OuputPatientData Yeah. It's like that. And the assignment required the name.

I guess that could be considered a class in a command-based architecture, where ReadTextFile inherits from (or implements) some sort of base Command class and it contains all the information the processing system needs to perform that action, but it's a stretch, and certainly not to be taught as "the norm"...

That's almost certainly what is being taught. It comes from the (very helpful) book 'Design Patterns' by Erich, Gamma, et. al. (aka. 'the Gang of Four' ... abbreviated everywhere to 'GoF'). It is useful in particular situations, and it has trade-offs. Professors should teach it, but I doubt they are advocating that it should be always done that way ... that's more likely students not grasping the nuance of when to apply the pattern.
