Yes, because you can code operating systems and whole entire game engines in C#. Within the realm of its applicability C is still a very good language. And, in fact, how do you think all of C#'s libraries are implemented?

Some programming tools NOT used by Real Programmers:

> Source language debuggers. Real Programmers can read core dumps.

> Compilers with array bounds checking. They stifle creativity, destroy most of the interesting uses for EQUIVALENCE, and make it impossible to modify the operating system code with negative subscripts. Worst of all, bounds checking is inefficient.

Quote:

If you ignore the fact that it's "structured", even 'C' programming can be appreciated by the Real Programmer: after all, there's no type checking, variable names are seven (ten? eight?) characters long, and the added bonus of the Pointer data type is thrown in-- like having the best parts of Fortran and assembly language in one place. (Not to mention some of the more creative uses for #define.)

I don't see an endorsement for C# made by REAL PROGRAMMERS! In other words, C# is a language for quiche-eaters.

@OP that/those is/are a/some really great article/s. Must-read for C coders.

It seems a biiiiiiiit FUDdy about UB, though.

In my experience, you only really run into UB when you already have a bug.

· Why would you try to shift a uint32_t by 32 bits?
· Why would you ever check if x+1 < x?
· Why would you malloc(INT_MAX)?

If you are doing any of these things, then you've already got problems, with or without UB. And UB doesn't really format your dog or send raunchy emails to the prime minister. That's just a fun thing to say.

People need to think about edge cases. And stop writing code so complicated that you actually need to think about sequence points. And don't use C unless you really need the speed (or are learning to use it, of course).

Well sure, it is edge-casey, but then it is written by a guy that has to deal with the edge cases :D

And I quite like the idea that UB causes nasal demons, it's a neat idea to reinforce that any kind of code could be generated (including none at all).

The Real Programmers article is still brilliant :D

Those last two posts were a pretty weird read for me not knowing much about C and having not read the articles.

I still only know AS 2 & 3, but at least finally got into Object Oriented Programming. AS won't do for Apps though, so sooner or later I'll need to get into Objective-C at least.

I've never used OC but I know someone that did for a uni project, made a game on the iPhone.
