OOP and the scope of a class, am I wrong?

[Dave Kreskowiak]

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!

Use the right paradigm for the right job. And I'll refer to this again for any who haven't read it: Stevey's Blog Rants: Execution in the Kingdom of Nouns[^]

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 :)

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.

Yes - you misspelled "tyre". ;P

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

professors are teaching that classes are effectively a single action like ReadTextFile

I hope what they meant (but probably didn't clearly convey) is a recommendation for a TextFileReader class (that derives from FileReader that derives from StreamReader) that has methods like Read() and ReadToEnd(). /ravi

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"...

[DT Bullock]

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.

Many people consider this a must read for OOP/class deisgn -

In my mind, a class is a noun, not a verb, essentially

For me, a class may be either a noun or a verb. As a noun, the concept represented by the class is a thing, and the class provides information and operations for that thing. For a verb the concept is a process, and the class supports that process. I guess 'process' can be thought of as a noun, but thinking of it that way adds indirection to my thinking.
