Bjarne Stroustrup Reflects On 25 Years of C++
eldavojohn writes "Today roughly marks C++'s first release 25 years ago when about six years of Bjarne Stroustrop's life came to fruition in the now pervasive replacement language for C. It achieved ISO standardization in 1998 and its creator regularly receives accolades. Wired's short interview contains some nice anecdotes including 'If I had thought of it and had some marketing sense every computer and just about any gadget would have had a little 'C++ Inside' sticker on it' and 'I'll just note that I consider the idea of one language, one programming tool, as the one and only best tool for everyone and for every problem infantile. If someone claims to have the perfect language he is either a fool or a salesman or both.' There's some surprising revelations in here, too, as his portable computer runs Windows."
C++ is popular for the same reason Windows is popular (and in fact, Windows' popularity probably fuels a lot of the popularity of C++): it is widely deployed, people know it, and there is a lot of legacy code that depends on it. Popularity does not make a language good, and I think we have enough examples: COBOL, FORTRAN, C++, etc. C++ has a number of glaring omissions from the standard, and worse yet, things in the standard that are now idiomatically avoided (see Effective C++ and Effective STL if you are interested -- auto_ptr certainly comes to mind). There are some really great languages out there, which just don't have the same non-technical advantages that C++ enjoys, and therefore never became popular among mainstream programmers.
Palm trees and 8
C++ is about freedom, features and performace. That is what makes it special and what matters in producion environments.
Objective, generic, functional -- its all there and accompained with the best preprocessor, macros and code generators by leading Intel, Microsoft, AMD and even Apple C++ compilers, but again the most important thing is that nothing is really forced upon you. No "automatic memory manager" or other "nany" and "dumb things down" features that create artificial limits, slow execution, unpredictable behavious and most importantly do not restricts you to somebody's elses narrow minded coding practices.
C++ is successful for one big reason: it provides most of the advantages of C with the conveniences of an object-oriented language. Performance is excellent (close to C, which with a good compiler is close to hand-written assembly in most cases) and there's enough capability that you can write just about anything in it, including things that you would never consider writing in manged languages (like device drivers or the VM for those managed languages).
The problem is that the developers of C++ have trouble saying "no". There are a bunch of C++ features that aren't really necessary, but that exist either out of legacy or because someone thought it would be a good idea.
Look at Google's C++ style guide: http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Inheritance
Like most users of C++, Google uses a severely restricted subset of the language. The thing is, most of what Google has left out is quite frankly unnecessary for 99.9% of C++ users. But we're all stuck with it anyway.
Once you get past some of the C-legacy anachronisms and restrict C++ to a small subset of its functionality, it's actually a nice language. The problem is that we can't take things out at this point.
