Really frustrated when moving from C# to C++
-
Mostly because of how pointers and references work, and also function definition seems very different. :((
C# to C++?! You shouldn't expect that move to be easy, and you should in fact be happy that you were not moving to C.

My observation is that people who discount the importance of knowing how things really work (i.e. how things work in the absence of an unseen, out-of-thread garbage collector) tend to be people who look at everything from a very PC-centered perspective. On a PC, or anything resembling a PC, it probably does not make sense for application code to need to do anything special just to effect proper garbage collection. But a real computer scientist, or even a reasonably good (i.e. versatile) programmer, should realize that not everything is a PC, and that there is value to being able to run things on devices that are not PCs (e.g. microcontrollers retailing for $2). This is just one of a whole family of spurious, PC-centric arguments I see on the Internet, which has, after all, become a network largely comprised of PCs. Statements like "every application should have logging" or "every application should be OO" fall into the same category. Such assertions really seem nonsensical if one considers the code that runs inside of digital wristwatches, DVD drive controllers, and such.
Interesting, I hadn't considered the problem it that way, and I think for your points are valid. That said, I've only really developed for PC and I've only really been a .net developer professionally, I enjoy tinkering with other languages and I miss c++, which I use to write my dissertation. I think the deepest separation is between those who like programming and computing for its own sake, and those who do it solely as their day job. I think a large proportion of the latter group fall into your PC-centric category as this is what pays and what is easiest to get work in. Got my 5 anyway!

I feel the same way about C++ to C#. I've found you still need to check for null just as often and C#, without the .NET library (libraries are really a different topic...IMHO), is hardly the C++ 2.0 most C/C++ programmers had been longing for. I would like a reinvented C/C++ without all the historical baggage but I'd like to keep pointers and references the way they are. I had high hopes for C# but I think they missed a great opportunity to "fix" what was wrong with C/C++ and instead ended up trying to "fix" what was wrong with Java.

Exactly: that's VB garbage collector's definition.

And even worse, pointers do exist in C# and work very much the same way.

That depends on a specific definition of some of the terms in the statement however. The following comes from the C# Language Specification in the Unsafe Code section. "The core C# language, as defined in the preceding chapters, differs notably from C and C++ in its omission of pointers as a data type. Instead, C# provides references and the ability to create objects that are managed by a garbage collector."

Why? STL has a perfectly good implementation of string handling.

So does ATL/WTL/MFC/Boost. My point was that String is not built into the language, so when you're bouncing between different project types, you're always have to adjust, because they're all a little bit different.

There are two ways to look at this, either: a) once you have figured out how pointers and referencing works (in which case you'll be a "man") --or-- b) you just give up as it is too complicated There is a very real difference between groups a & b. The people who write .net understand this stuff, they handle it for you (for the most part). If you have any interest in your craft, it will be good to get to grips with this stuff. When the penny dropped for me (back when I was at uni) it was like a moment of zen enlightenment, it tied together several parts of disparate courses: it bridged the gap between chip design & assembler and the higher level stuff we'd been doing elswhere. Although I found it interesting for its own sake, I still find this stuff useful ten years on. It makes learning new langauages easier for one thing.

I recommend Data Structures and Algorithms Using C++ (Second Edition) (one is available in new condition for $25). Pages 3-4 and 15-30 cover pointers and reference variables very well (I was just reminiscing yesterday about my C++ days and read a few pages from this book :-O ).
