Recently I made a post about some things in Java that I find to be a bit of an issue. The artcle was reposted on Javalobby and it started an interesting discussion in the comments section. Among other things, one comment in particular struck me as disconcerting:
When you use a language you should ask yourself what is the feeling of it. C++ is an elitist language with strong roots in the procedural C (that should compile in C++), and a big focus on performance. Java is a full Object Oriented langage inspired mainly by C++ and smalltalk, which was for a long time pretty slow, and focus on writing big maintainable programs via simplicity and strong typing.

Specifically the part about C++ being elitist. Now, I love C++, so of course I am biased. However, I never thought of it as being elitist. The funny thing is that the syntax of C++ is very close to that of Java, does that mean Java is elitist? As far as I see it the real difference is that Java: offers you loads of libraries, memory management, and it allows the coder to not have to think about pointers. Lets look at each of these issues.
The first issue, of libraries, I don’t really consider much of an issue. Especially if you use open source libraries there are hundreds of libraries which are readily available. Certainly the Java libraries are nice, and most, if not all, are guaranteed to be cross platform. However, many of the C++ ones are as well so I also consider that argument to be a moot point. The fact that you have to compile them for each different platform can be a problem at times, but I consider it a minor problem especially given the speed of modern computers.
The second issue of memory management is something that goes to Java’s favor. I think, however, that it is a minor issue in the scheme of things. Once you understand the basic idea of memory management, and as long as you use a good programming style which favors allocating and freeing memory in the same place, this isn’t as big of a deal. I have written that you can leak memory in Java too, so Java is not free of this nuisance either! Therefore Java coders who think that are impervious to problems with memory are just kidding themselves.
Third is the fact that in Java you don’t deal with pointers. Or, rather, you don’t have to think about them even though you deal with them all the time. This is more personal opinion than anything, but I never found pointers to be that difficult of a thing to deal with. Once you get an understanding of them it’s really a trivial matter. I know that some people make a fuss because you have to always be thinking ‘is this a pointer to an object, or the object’, but that consideration has never slowed me down. You make note of it once and then it stays the same throughout.
So what is it about C++ that makes it elitist? Is it the people that write code so convoluted that only an experienced pro can read it? I think this could be a big part of it. No matter what language you use people can always write unnecessarily confusing code. Languages like Java try to help prevent this, but I’m sure it can still be done. Having access to pointers can lead to code that is difficult to read, but I think the problem there has more to do with the coders than the language. Programmers should be wise enough to write readable code, and not blame the language.
Do you blame English when you can’t spell a word? I mean… silent letters, what is up with that? No, you probably blame yourself for not having put in enough time to learn the proper spelling. So why should we blame C++ for people that write obfuscated code? At the end of the day it all comes down to the coder, and whether they want to write good code or not.
The bottom line is that I don’t consider C++ an elitist language, but rather a language that with some extra consideration can be just as easy to code in as Java.
