When the code of a project is getting bigger and bigger you need classes to find some order. And also you have reoccuring tasks for what classes are best.
Tip: a function should NEVER be greater than what you can read on your screen. Everything else is "Spaghetti code"

YES!
The first thing I do when writing new code is design an appropriate class interface. For a class designed to be non-inheritable (e.g. a complex number class), the interface might be merged into the implementation. If the class is inheritable or polymorphic (e.g. the canonical Shape class), then the interface will be virtual, and separate from the implementation(s).
Working this way forces you to concentrate on the design, rather than rushing to a (possibly) flawed implementation.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Yes I do. I do work in embedded real time systems too, albeit loose real time based on extreme computation speed and delocalization of core functionalities rather than dedicated system, and C++ is as bit as powerfuls as advertised.
Most of our codebased is neither encapsulated nor abstract and that's what my team does in the rare R&D time we have allotted: push functionalities that now are global static unssecure and sparse in a full OOP hierarchy where components internals will be independent from the interlas of other components. Maybe in a handful of years we'll be able to ditch the old, cramped and contorted VB6 interface (whic as of now contains a lot fo, eguh, logic) in favor of something new, maybe C#.

With no connection to languages I do think OO when thinking of software design...

I see no problem with that, when architecture is well defined you don'T get to any of those questions. Using patterns also helps keeping stuff clean and simple. That's what it is about, keeping stuff clean and simple.
Objects <-> Logic <-> UI does a good job on keeping stuff separated and makes it more understandable.
So for example, everything that has to do with database access gets in a separate class for that. You put things together that belong together and keep all stuff to that at one place, makes it easier in my understanding.
I think this could also work for you, if your machine has different physical things. Like this is only for lights, this only for left arm, this only right arm, this only treadmill and so on 
(Obviously only makes sense when left and right arm do different things)

All good comments. In my rant area, we don't have performance issues. When talking to "the machine" (I like that term), some data items HAVE to be coordinated. Rather than putting it in a class, I have it in multiple places. So, I have bugs in multiple places.
I also DESPISE globals. Sure, like goto's, sometimes they just work. And this code is coming from people who ought to know better.
Well, you've cheered me up. At least some consider these things as useful.

I try not to. I've dabbled a little.
I've done a lot of C, and what I don't like about C# is that everything must be in a class. (And yet no multi-inheritence.  )
I prefer to use the right tool for the right job.
And please stop referring to VS as a compiler.

Ironically, that view is one that prevents deep adoption of C++ in the embedded world. There's a widespread perception that C++ includes a lot of overhead that embedded applications can't support. The perception is mistaken. Any loss in performance due to C++ constructs (virtual function calls come to mind) is more than made up by improved engineering. If it's really that much of an issue, C++ can always be treated as "a better 'C'". For that matter, performance requirements that stringent call for custom hardware anyway.
I'm dealing with this myself at the moment. A few months ago I inherited one of our long-term products, which is written in 'C'. The code is over 25 years old. It started life running on two single-board embedded computers, and now runs as a service on a Windows box. It's awful. Globals everywhere. Code reaches up the skirt of data structures without regard to access safety. Hell, it doesn't even follow good structured programming practices half the time. My intent with this crap is to answer questions if necessary. I ain't touching the code with my ten foot pole or anyone else's.

Well, I personally think we always do an OO implementation even when we aren't using an OO language.
It just turns out soooooo much messier and hard to maintain if the language lets you shoot from the hip too much.

I totally agree that abstraction and encapsulation are vital - but... there are more ways to skin a cat than just putting it into a class Structs and functions, classes or whatever you want to use, are all just implementation details - appropriately splitting your application into cohesive parts with low coupling is what matters.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

C++ was used to teach Object Oriented programming in a University Class I took in Computer Science back in the late 80's. I found it was easy enough to pick up if well presented. I was able to get things to work and that is a big plus. Modern tools are even better than the ones I used then. It also offers Multiple Inheritance which is also a major concept of OO, but also quite a complication if combined with Polymorphism at the same time. If you want an easier language to learn, then I would suggest C# since you can get a good free IDE from Microsoft for that.

Classes do not exist. Good design does.

...and if it ends with a newline, it is no longer the last line.

lol, correct. The part that had me lost was VS2008 helping me.

In my opinion... every code file should begin and end with a blank line. I don't recall any version of VS hindering that.

Why? Whitespace at the beginning and end of the file are immaterial to the compiler.
Wait a sec. Let me guess. You produce listings by doing this:
COPY *.CPP LPT1: don't you?

Maaaybe...  That's "documentation".
Historical reasons, old editors that loaded slowly, typing before it was ready.
And you know I like whitespace.

I was copying a large amount of files from one drive to a USB flash drive on a Windows 7 box. I selected all the folders and files, copied and pasted to the target drive. The system gave me an estimate of 23 hours to finish the copying. At the point when roughly 80% was done I had to leave so I decided to cancel it at that point.
Later when I was back I wanted to continue the copying. I was lazy so I selected all the folders and files again (even though 80% of them were already copied), copied and pasted to the target drive. I expected to see a message box showing "there is already a file with the same name in this location", and I would utilize the GREAT improvement MS had made over XP that I could just select "Don't copy" and "Do this for the next xxx conflicts" so the rest of the files would be copied. Instead, I was greeted by this message: "There is not enough space on xxx. You need an additional 22.0 GB to copy these files", with a "Try Again" button and a "Cancel" button.
I think they should give the users another button "Try to copy anyway" so they can copy as much as they can. In my case the free space is large enough to hold the rest of the not-yet copied files! Besides, sometimes people want to stuff as many files as they can on a drive. All my files are small ones, the remaining space is not big enough for all the files selected, but it can hold thousands of these small files.

Looks like you made the same mistake that many of us made: you expected windows to get better, not worse.
Anything that isn't a security update, and that has been checked to contain nothing but security updates, should be ignored.
