It's very easy to hang yourself in C, but it will all be because of accidents and the all of the problems you cause will have the same fundamental cause (a bad pointer).

It's very easy to hang yourself in C++, except it will be because you used some language feature (actually, it'll be more like "you used some huge set of language features") that you didn't fully understand and now you've dug an inescapable hole. I really never got into the whole template thing or anything like that--I see the point, but I've never really seen a huge benefit in what I've worked on. So, I code in C++, but I use it as C with a few things that make it a lot more convenient (some OO, operator overloading, references, the STL, etc.).

Is the Ansi C Programming Language a good book to learn C from if you're familiar with the basics of programming, or are there better books to start with?

is this Kernighan and Ritchie? K&R is *the* book

Yes, but is the one I'm talking about the right one? I know the K&R "style" is supposed to come from the first edition, and that the second one is the ansi style. Should I be using the first or second edition?

absolutely use the second edition

Heh, because I can't stop myself from wanting to mess with one or the other. So far it hasn't really been a big deal, but if it gets to the point where I can't separate the two, I'll stick with one.

Stick with C at first, because you will get confused between pointers and references and arrays and STL containers and new and malloc and all the things they do differently. Once you can look at C++ and see how it's built on top of C clearly, it will make a lot more sense.

What the gently caress, Qt 4.4 supports futures? Holy poo poo.

Wow, the whole QConcurrent framework looks fantastic.

Any idea how it's implemented on the backend?

if (c == ' ') wouldn't work?

I know you're learning C++, and not straight C, but have you considered getting a copy of K&R? (It covers this kind of stuff very well.) It might be a huge help to you.

Edit: Then again, trying to learn C++ while reading K&R might not be a great idea. Is there some equivalent the C++ goons recommend?

honestly, K&R is always a good idea. I think learning C is a prerequisite to being a competent C++ programmer, plus K&R is so clear and concise that it's not really a bear to get through. as far as C++ books go, I'm fond of the Stroustrup book, but that's mainly because I can hit people with it. that IS a bear to get through, as it's closer to a reference book or language specification than a tutorial, but if you can make it through, you will know C++ pretty drat well.

(plus you can beat the poo poo out of people with it)

Learning to program by reading K&R is like learning French by reading Rimbaud. It can be done, but you're going to be confused, frustrated and it'll take you 3 times longer than necessary.

what? K&R has some pretty straightforward examples in the beginning, but I will admit that by the end they can be almost too concise. but then again it's the kind of book you can read many times and still get something out of it when you're a beginning/intermediate programmer.

Unless you're on Plan 9, this is how every compiler does things by default. The C and C++ runtimes (msvcrt.dll on Windows and libc.so, etc. on Linux) are dynamically linked to your program unless you tell the compiler otherwise.

Plan 9

Could you give a concrete example? fmod(12.0, 3.0) == 0.0 for me. I would expect examples modulo some integer to work fine.

depends on how big the integers are and what floating point precision you're using...
