C is a better language than any language you care to name.

Maybe, but at least it's consistent with the
goto/label syntax.GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them.

Have you read the article?

C can be plugged into any application in any language. The author is aware that C itself lacks libraries and he does mention it. So what was your point again?
Colborne_Greg wrote:
Plus it looks pretty.
Ah that. :doh: Ok, seriously. If you meant it has a better readability, that was mentioned by the author, too. So, again the question, what was your point?
Colborne_Greg wrote:
For example the "with" operator is in Visual basic but is not in C.
And it's in Pascal. So what? Again, the author made a point that other languages offer more (and often more complex) language elements - but that doesn't deterr him from listing a number of advantages of the language C that you failed to address entirely. Disclaimer: I don't actually agree with the article. I just wanted to point out that the article already pointed out or implied everything you said, and you did nothing to argue against it.

Your signature has a line about GOTO The goto fail example is a major fail in general for the C language. The goto is the first thing every programmer should avoid, but in this example the GOTO's are used correctly, but its a limitation of the C language (one of the dumbest things in history I might add) Visual basic .net is C with English words and no bracket issue, the GOTO fail would never had been an issue in VB.

You are arguing against something I never said. Specifically, nowhere did I say that the precompiler isn't part of the language. More generally, my point is that the information about the size of the array is known only by the scope of the array declaration at compile time; it is not contained in the array itself and available at runtime. In C, an array and a pointer are, for all intents and purposes, synonymous (with the exception of this very narrow edge case.) So, the [partial] function declarations
a(const char* p)andb(const char d[])mean the same thing. Doing asizeof(d)for the latter doesn't tell you anything meaningful about the original array. This also means that you can take an arbitrary pointer and use array syntax on it. i.e.p[3]. This gives C an enormous power and flexibility found in few other languages. Attaching any other information to a pointer (or array) changes the very nature of what a pointer is and adds overhead that is often not desired nor wanted (and if desired, you can easily create a struct (or class in C++) with that information contained in it. This very flexibility means that arguing that arrays are problematic in C is a strawman argument.) -

Rather certain that the precompiler is in fact part of the language
Yes, and as he said in his response, he didn't say otherwise. Some points I'd like to make are: A language is defined by its compiler (not the other way around). DMR probably could have made C without a pre-processor; I see no reason that C has to have a pre-processor other than that it does have a pre-processor. The existence of D and C# may support this view. I have seen (I don't remember where) at least one argument that the C pre-processor acts on a different language than the C compiler does; and I am in about 90% agreement with that point of view. I like the C pre-processor; it's really just a text processing utility -- it can be used for purposes other than its primary usage. (I even use it with C# -- Implanting Common Code in Unrelated Classes[^]) Unfortunately, it also has some functions (e.g. sizeof) that are tightly bound to C. :sigh:
jschell wrote:
limiting oneself to just the "language" then C is in fact useless, since one cannot in any practical way do anything useful with the "language"
You may be arguing that the language is pretty limited without libraries, and that is quite true, very little can be accomplished without at least printf -- I have written a simple program that calculates a value and returns it from main, simply to demonstrate that something, no matter how pointless, can be done without linking in any libraries. However, I think the article was also pointing out the ease with which a developer can leverage a multitude of libraries with C. Just the other week I was playing with ODBC, and linking in only the ODBC libraries and not the "standard C libraries". Of course, doing so still requires the pre-processor, as the Creator intended.

No. Compiler theory is a very complete area of study in computer science and most perhaps all successful languages build upon that. And within compiler theory the compiler is an implementation, nothing more. And in terms of C, although perhaps not specifically this discussion, there are many ambiguities which the compiler is allowed to define but others which it is not.

With something like 20 years of C/C++ experience I am pretty comfortable with what the language is and isn't.

Well first I was noting a technical point not a subjective one. Second K&R when it was written was written in a different style than VB, so even if the author(s) of VB made a technical point then I would be less inclined to accept it (which is true of C# and Java as well.)

You've completely missed my point. My sig should have made it obvious I abhor the use of goto. I merely pointed out a possible reason why
casemay have been specified the way it is. Not that I wouldn't like to bangotofrom the language entirely. And not that I would miss theswitchstatement for that matter (not much anyway). It was just a statement about the consistency of the language as a whole. As for your love of Basic - to each their own. It certainly has it's use for certain kind of applications. Me, I've been working on processing-intensive applications for decades, and no Basic dialect whatsoever, not even the compiled ones, would ever have served the purpose. That said, I'll remove the link from my sig: as you've pointed out, the main reason for the problem isn't so much the use of goto - it is the fact that braces (or other block markers) are only optional after control statements, combined with an unlucky duplicate line of code - that this line contains agotocommand is just happenstance, many other commands would have caused havoc as well.

Also to answer the more specific question, I don't think the language has anything to do with 64K limits, for strings, or otherwise. Those are all implementation details of specific compilers.

It sure looks like you are proposing that Pascal is a better language than C, based on certain criteria. Pascal is indeed a very good language and I really liked it when I was using it in college, but I haven't used it since, and I can't even read/understand the code I have from that period.

That may well be, but is it not part of the Pascal language spec that a string is limited to 255 characters because the length is stored in the first byte of the string? I suppose not every implementation uses 8-bit characters, but it still imposes a definite limitation other than "available system resources".

No, you have completely missed the point of my message. Go back and re-read it. What I am saying is that, a lot of people bash C but those same people don't realize that whatever language they prefer is probably written in C. So I challenged the readers to name a language that was not written in C.. because it's hard to do. Most new languages, VB, JavaScript, Python, Ruby all written in C. However, there are languages not originally written in C, although they are old. Pascal is one, which is the one I mentioned to get the ball rolling. You're being unnecessarily antagonistic without understanding, or taking the time to read, what I'm saying. I suggest you drop it.

Okay, although it's true that one can implement Pascal differently, you're right that it's limited to 64K (or 32K) in length for strings. But I really don't think that's a good example of Pascal's inferiority over C. There's advantages to counted-strings, and I've worked in environments where actually simulated Pascal strings in C for efficiency (i.e. you can easily get to the length). COM BSTRs use a similar structure, but store 32-bit lengths. And the reason I don't think it's a limitation is because if you needed a string that long, C's null-terminated string is hardly preferable. You likely need a different data-structure (rope, array of strings) to do whatever you're doing anyway. Or, more likely, it's that big, it's probably a memory buffer that you'd manage using address and count. As a reminder, my initial post was not stating Pascal is better than C. It was to point out that many of today's languages are written in C.

Pascal pre-dates C slightly, it certainly pre-dates C's popularity. COBOL, Fortran, and BASIC also pre-date C.

Perhaps you just don't find the limit to be a hindrance. I never had any trouble with it either, but I never had to use Pascal to do real-world development. Just as .net strings are limited to 2GB -- it's a limit, but it hasn't yet been a hindrance.
