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

I agree that compilers do produce good code: but they can't interpret what the author is trying to get the hardware to do and that means what they generate can be spectacularly inefficient. I had this problem with the ARM development kit (which was stupid money) - I needed to generate a specific wave output with my data to match the hardware it was interfacing to - and the C / Embedded C++ code just wouldn't do it no matter what I tried. In assembler it was trivial (but I eventually fitted a second PIC processor just to handle the interface - and coded that in C :laugh: )

I agree, I love programming in Assembly, but I'm not sure I would beat the compiler, I'm just an enthusiast, don't program in it professionally. I also love C/C++ and was wondering if the ARM compiler you used support mixing up C and Assembly, like:
__asm
{
INC [EAX]
MOV EBX, [EAX]

:) :thumbsup: VB Code is actually very easy to understand but you're right, the code written by some people in VB is atrocious.
There are only 10 types of people in the world, those who understand binary and those who don't.
you can write bad code in any language, and as a programmer of 35 years ive seen more of it than u can shake a stick at, and as far as the VB v c# argument goes, it all compiles to the same IL anyway, the skill is in the programmers interpretation and solution, not for c# snobs to blindly say that its somehow 'better' - its a subjective argument
-
C# is better because # is composed of four pluses, therefore 4 times better than C: ++ ++

It's a good language, but in the modern world it's a bit...outclassed. If you want small tight code for embedded work, then assembler is probably a good bet - though C is very useful there, it does tend to generate bloated code compared to that produced by a good assembler programmer. The C code will be produced faster, but it'll need more RAM, more processor, more...in embedded work you don't always have the luxury! If you want desktop work, then C# or C++ have so many massive advantages in terms of OOPs design that there really isn't any comparison. It'll take you a lot longer to write the same app in C, and it'll almost certainly be harder to maintain. If you want to write a website, then good luck doing it in C... It's a product of it's time: it was designed to be "better than COBOL and FORTRAN". But the world has moved on, and the "competition" is a lot more sophisticated now.

Agree if you're code is WOUF (Write Once, Use Forever). The choice depends on what the engineering constraints are. If I want to accommodate the hardware people having an upgrade path, going from an 8051 to an 80186 say (to use an archaic example), then portability and reusability are the constraints and C makes much more sense. I really don't want to do the SSDD shuffle for the rest of my egregiously unnatural life. :) ("bloated code" used in reference to "C", Gracie? Oh! I get it. It's a pesky relativity thing.)

It's like just as soon as computers get faster, we want to make the languages more bloated. That way we never enjoy the new speed, we simply keep things the same and have a new cool shiny layer that sounds technical to toss on top of it. I've never made a programming language, but when I think of something like Ruby, which has some nice features, and then I think it's slow as dirt so I'll never use it. Just because CPUs are faster doesn't mean we can waste cycles, otherwise it's always a game of catch up.

True, only if you're doing something extremely CPU-bound. However, the vast majority of current application are highly user-interactive, where , by far, the really speed bottleneck is the user.

Let's start with this. Name any other language other than C. But there's a catch: the language's primary implementation must not currently be in C. So Java, JavaScript, Python don't qualify since they're canonical implementation is written in C. Also, self-hosting doesn't count; in that case, it must not have been bootstrapped with C. I'll start -- Pascal -- first version of Pascal was written in Fortran. Next...

The assembly guys said the same thing of C. I'd be willing to bet the patch-cable guys said the same thing of assembly. Do you really want to program your current applications using patch cables? How about assembler? It isn't (or shouldn't) be about adding cool-sounding technical layers, each language evolution allows the computer to do more of the mechanical grunt work, freeing us to spend more time doing the creative part. I don't know about you, but I really appreciate that.
We can program with only 1's, but if all you've got are zeros, you've got nothing.

I totally agree with this, but only if the evolution gives us a real gain. Something like sugar coating at the price of performance I don't agree with. A legitimate paradigm shift I could understand.

Often, what has appeared to me at first as a sugar coating, turns out to be a paradigm shift in thinking that I didn't grasp. Not always, but a lot of times.

Visual basic 2013. It can utilize every C, C++, and C# library. Plus it looks pretty. For example the "with" operator is in Visual basic but is not in C.

No, it's because it is a half tone above C.

Ah, but you can optimize those pluses and make the # with only two distorted pluses.

As already noted, one can write terribly in any language, programming or "natural". If writing systems level code: C or C++ If writing business system code: Modern COBOL If writing science/engineering code: Modern FORTRAN. If a masochist (or given no choice): Assembler If writing modeling system: (Probably still) SIMSCRIPT If writing WEB pages: HTML/CSS, but many IDEs now available to make this easier. 50 years of programing using 30+ languages including BASIC, VB, JOVIAL, HAL, 15+ assemblers, PL/1, APL, ALGOL, C/C++, HTML, JAVA, PYTHON, PERL, etc.

Any time anyone thinks that one technology is "better" than another then first they need to define what "better" means. And since the statement doesn't limit itself to which other language is compares itself to it is going to fail because for any measurable attribute there is going to be some language which is in fact better than C.

No the ARRAY does not. The declaration does and thus the precompiler) and sizeof(), but not the array itself. To illustrate, the function:
void _function(const char r[])
{
printf("%u\n", sizeof(r));
}Will print 4 or 8, depending on the size of a pointer, when you call
_function(q);. Added: Moreover, an optimizing compiler will likely pool both strings and use the same pointer for both operations (especially since it's clear they are both const.) Again, the sizeof() is handled by the precompiler, not at runtime.Joe Woodbury wrote:

Rather certain that the precompiler is in fact part of the language since it is in fact part of the specification for the language. If you wish to another definition for "language" than the specification then you would need to provide one. And if one wants to be specific then at least in my edition of "C Programming Language 2nd Edition" the preprocessor is part of the main language definition (not an appendix) and the section specifically starts off with "C provides certain language facilities by mean of a processor". So if K&R thinks it is part of the language I am going to take their word for it. Or perhaps to put in in another perspective, 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". Thus it can't, again in a practical, real world way, be "better" than anything else.
