Latest Proposals for C++0x
CodeDemon writes "It looks like the ISO/IEC JTC1/SC22/WG21 working group has made some headway in reviewing new proposals for the C++ language. The long anticipated upgrade for C++, C++0x, may be just around the corner. Head on over to check out the proposals yourself."
I too read it as "C++ followed by some hex number to be named later", but after skimming very quickly through the proposal, it seems they meant "C++ (20)0x, where x depends on whatever year the spec/implementation/whatever is released". Or, at least, that's what I think it means.
I can understand where you're coming from. C++ is a complex beast. I've been using some form of C++ for over 10 years (well before it was standardised) and I still don't understand everything about it.
With that said, it's an extremely powerful and flexible language. Very much more powerful than Java or C#. The complexity is mostly due to its flexibility. You can do (almost) anything with it. Of course, we can argue whether that's good or bad.
I think C++ can learn from Java though. The default should be to pass all non-built-in-type function parameters by const reference and the programmer has to specify otherwise (basically opposite of the way it is now). That would clean up the code a whole lot since 99% of the time that's what you want anyway. And the standard C++ library should have some sort of garbage collector available.
Another problem I have with C++ is that even with all its power you have no way to get to the "left hand" variable of operations. For example, if you have a matrix class you can overload the "+" operator so that you can do things like "matrix3 = matrix1 + matrix2". However, that's not going to be very efficient (assuming that's why you're using C++ in the first place) because there is no way to get to the matrix3 variable from inside the + operator. That forces you to use a temporary variable to add the two matrices then copy by value the whole matrix after adding matrix1 and matrix2. There are tricks around this problem but none are clean.
The ratio of people to cake is too big
I think C++ is quite useful, and I'm not a "2 week IT person", not that I think they are necessarily inferior beings. On another note, most IT people I know tend to make the most use of Perl/Ruby/Python since it solves most of their problems quickest.
Straight C is my favorite tool and what I use for embedded programming, quick hacks and performance constrained work. Every time I try to do a large application with it though, I find myself thinking "you know, they already did this exact thing with C++, and I'm going to spend 2 days re-inventing this and testing it".
I use tidbits of Assembly (80x86, MIPS, Arm, PowerPC, what have you) in embedded systems for device driver or performance critical sections. As a HW engineer I tend to use this a lot in bringup of new designs, especially "very new" designs that don't necessarily work and every instruction is important.
I use C++ when I am building a very large, flexible application where I use many types of data structures and need it to get up and running in a short period of time. I like this language for "serious application" programming.
I use Perl to manage my file system, do text processing and other maintenance hacks.
I use Java for simple GUIs that often work as a front end for serious endeavors.
I use TCL/TK for ASIC/FGPA debugging (simulator interface) and test suites.
I use fortran less and less (often I convert to C) for purely numerical computation. Gems of knowledge exist in fortran code for optimized matrix related algorithms that are highly useful in 3D visualization.
I have not found any practical use for Pascal or Lisp lately (the latter is useful for emacs, but I rarely mess with it).
The point of all this is that much like you wouldn't use a screwdriver to drive a nail through wood (unless that was all that was available), you would tend to use whatever tool is best suited to a task. Us engineer types are supposed to be tool-makers and users of the highest order. It surprises me when I hear one of us suggest we should use our favorite tool to the exclusion of all others.
I do not like C++ in terms of the performance and memory impact it infers, but when building large applications I do not have time to re-invent a linked list for the umpteenth time, nor do I want to debug every different link list in my code, there are much harder problems to solve more critical to the success of my project. That said, C++ (and C for that matter) is lacking in some very important things. Among those I think are critical are: multithreading, network stack framework (platform independent that is) and GUI framework (platform independent!). If you read the article, you'll see mention of at least two of those things (we need a standard platform independent GUI library dammit!)
In practice, C++ is finally getting to the point where various compilers accept the same code. That after 15 years or so. Now they want to shake it up again?
