C/C++ Back On Top of the Programming Heap? 611

Drethon writes "On this day in 2008, a submission was posted that C/C++ was losing ground so I decided to check out its current state. It seems that C has returned to the top while Java has dropped by the same amount, VB and PHP have dropped drastically, C++ is holding fast but now in third place and Objective-C and C# have climbed quite a bit. 2008 data thanks to SatanicPuppy: 1. Java (20.5%); 2. C (.14.7%); 3. VB (11.6%); 4. PHP (10.3%); 5. C++ (9.9%); 6. Perl (5.9%); 7. Python (4.5%); 8. C# (.3.8%); 9. Ruby(2.9%); 10. Delphi (2.7%). The other 10 in the top 20 are: JavaScript, D, PL/SQL, SAS, Pascal, Lisp/Scheme, FoxPro/xBase, COBOL, Ada, and ColdFusion."

      I would expect that a lot of companies are probably working on importing their legacy systems to work for the new 64 bit systems.

      a good amount of legacy systems are written in C, and most of those C written programs are fairly optimized for their platform they were designed to run, and we are starting to switch to 64 bit and multi-core architecture.

      You're more or less paraphrasing an email I recall from Linus back in '94 when the 64 bit Digital Alpha port was just beginning. Of course that's 18 years ago not anything new. I think we still have many more years of the "64 bits is new" meme left. With more GOOG effort I could probably find that email. Or it might have been an old Linux Journal article about the alpha port rather than an email. Hmm.

      I was pretty late to the conversion to 64 bits compared to most people in the biz. I don't think the debian amd64 port was released until 2007 ish, I think as part of Debian 4.0/etch, although I was using the amd64 port as "testing" (before it became "etch") for at least a year or two earlier.

      Some of our amd64 hardware at work is considered legacy now, just because its so old.

      I remember in the early years of the 32/64 bit conversion, like half a decade ago, running legacy non-free software like the 32 bit flash player on a 64 bit OS was a pretty interesting problem, but it was all solved a long time ago, so its not interesting anymore. I would imagine someday in the future the windows folks will have similar interesting experiences when they catch up to linux, as they always eventually do.

          Total nonsense. Almost every game these days is written in C++ and while they all vary in the amount of applied OOP and generic meta programming, the fastest ones use a data driven approach because OOP is SLOW - raw C++ makes dealing with ONE type of object easy, but it doesn't help dealing with performance issues when you have MANY objects. I.e. Template Bloat, lack of virtual dead stripping, and inflated deep hierarchies, to start with.

          C is a good language because it forces one to think about runtime performance. When you have some junior coder sticking a virtual function call inside a for loop because he doesn't the three levels of pointers being applied the problem is not the language per say, but programmers who don't understand enough of the hardware to know "There Is No Such Thing As A Free Lunch"

          Higher level languages tend to help minimize *developer* time, at the expense of run-time.

            Higher level languages tend to help minimize *developer* time, at the expense of run-time.

            If you're really interested in run time, you should be more concerned with asymptotic ("big-O") performance rather than basic code efficiency.

            Also, no amount of speed-up makes up for code that is wrong. The proper reason for choosing a higher-level language is that its readability contributes to correctness.

            First, they're mostly written in C++ because you don't prematurely optimize. Its the root of all evil, as Knuth said. Then, you go back, and you find your extremely critical sections, your bottlenecks, and THOSE you write specific libraries in C to optimize.

            However, modern C++ means to take advantage of modern constructs, like smart pointers, and modern containers, instead of using unsafe and non-bounds checked arrays.

          When you write C++ as though it were C++, you get really bad, terribly inefficient code. If you need to extract maximum performance from your code, a C-with-classes approach to SIMD & multi-core optimisations tends to lead to better results imho. It's very difficult to adhere to what most people refer to 'good C++', because 'good C++' implies nicely encapsulated objects. This doesn't really work so well when you have 256bit wide SIMD registers. Suddenly you find your C++ classes are actually maintaining the state of 8+ objects, and then some of the idioms start unravelling. OOP is currently being stabbed to death by concurrency & parallelism, and there is nothing anyone can do to save it.

    • I think people need to learn that all languages just create a bunch of machine language and is mostly just statements, loops and branches so there isn't a great amount of difference between any language. Anything you can make in Java or C# (are these truly high level these days or more of a medium level?) I can do in C. The only difference is I have to implement how these features are done in C (or find a library) rather than using language features. Not saying its better, just saying it is all ultimatel
    • by Artraze ( 600366 )

      With C++ basically being a superset of C, I wouldn't say that's entirely true.

      Regardless, though, when you look at the wide world of programming languages, they are _far_ more distinct from everything else than they are from each other. Java, C#, Python, Ruby, JS, HTML(?!) I can't think of a single mainstream language aside from "C/C++" that uses pointers lacks a garbage collector. So in regard to practical application and required skills, they are effectively quite similar.

      My impression is that Java will eventually relegated purely to in-house software, for large companies that are heavily invested in Oracle. Most of the goodness of Java comes from the Java API's, and these are on a legal battle. Most OS's are already not including the platform by default. At the end, for independent software companies, and specially for small shops, it feels too risky to invest one's time in learning or keeping up with a language that is controlled by a suing-happy company. As much as I despise Microsoft's ways of polluting languages (remember J++?), I think they are orders of magnitude more trustworthy than Oracle.

    A shout goes out to this site [hammerprinciple.com] which actually does a pretty good job of comparing all the languages on 'subjective' attributes such as "I find it easy to write efficient code in this language" (C being top here), or "Code written in this language tends to be verbose" (Cobol and Assembler are worst here, but Java is 3rd place, and that's bad considering it's meant to be a modern higher level language).

    You can even click each language and see what comment it is best for. For example, Haskell is top for "This language has a strong static type system" and "When I write code in this language I can be very sure it is correct". Meanwhile, something like PHP is top for "I am sometimes embarrassed to admit to my peers that I know this language" and "This language has many features which feel "tacked on"".

      Phillips screwdriver - Obviously Ruby. The mythology is both came from Japan, although phillips doesn't sound very Japanese, in ye olden days stuff made in America had slot screws and stuff made in Japan had philips screws, so obviously phillips came from Japan. Also more ruby is probably being written outside Japan than within, now a days, but I still hear people claim Ruby is japanese.

    There is definitely movement away from Java and toward C/C++ for some types of software. Applications bottlenecked by memory performance, like databases and high-performance codes, will often be faster than a language like Java by integer factors. When people assert that Java is about as fast as C/C++ they are talking about code like tight, CPU-bound loops. However, Java is wasteful of memory and CPU cache lines in a way that C/C++ is not under normal circumstances which has a significant adverse impact on the performance of some codes.

    On recent processors, memory performance is a bigger bottleneck than CPU performance for performance-sensitive codes. The throughput of CPUs has grown faster than our ability to keep those CPUs fed from memory. In the supercomputing world this started to become evident years ago; memory benchmarks like STREAM became more closely correlated with real-world performance than CPU benchmarks like LINPACK for a great many algorithms. The resurgence of C/C++ is partly driven by this reality since it makes memory optimization relatively straightforward and you can receive large gains relative to Java for modest effort.

    A smaller but also important driver away from Java is the GC. The increasing focus on "real-time" and predictable latency for applications like analytics and database engines is complicated when Java's garbage collector is inserted in the middle. This is a chronic point of pain for some applications.

    I developed Java for years but my latest project (a real-time analytical database engine) is being written in C++ for the above reasons, among others. Writing high-performance applications of this type is actually pretty painful in Java because you end up doing unnatural things in the language to even approach the efficiency of conventional C++. Anecdotally, many of our C++ developers were doing Java until recently so the statistic does not surprise me.
