Indeed, since its output is needed to index into cellGrid, it will always be called first.  What is not defined behavior is the order of evaluation of arguments to a function.  So if you had code like this:

Code: [Select]

some_function(function1(), function2(get_argument()))

get_argument will always be called before function2, but you have no way of knowing whether function1 or function2 will be called first.  I don't think it's even defined behavior whether get_argument will be called before function1.

Biology stuff is so interesting The first genetic drift thing happens because it satisfies all the conditions for genetic drift, especially a small population size (only 500 members), random mating and no gene flow.

I just made the simulation insert a random creature every turn, and there
s no noticeable fixation yet.

Hello guys,

I have just done about a year of c and about the same of python and done about a dozen odd projects and i wondered where i should go next because i want to write operating systems. So i read a basic 8086(not i386) assembly tutorial but it seemed not to have taught me much past general purpose registers and segmented real mode memory address (segment:offset). What i wanted to know is a few things:

-Where can i find a comprehensive x86 Assembly pdf or tutorial for either windows or cygwin?(my linux box is in the same                          room as the xbox and the sounds of call of duty are really annoying)

-Would it be a better idea to read the intel handbooks on the subject in lieu to a tutorial?(i don't know whether standard intel syntax is more applicable to GAS or NASM)
           
-Where can i find free books or documents apart from osdev.org on the subject?

Thanks

Back when I was still interested in OS development, I got 99% of my information from osdev.org.  I don't remember there really being any other decent quality sources.

For your other questions: I'd recommend definitely starting with tutorials, probably from osdev.org, over just diving into Intel's manuals.  They're thousands of pages long from what I recall and don't tell you many of the intricacies of anything beyond what the assembly instructions do.  Tutorials will tell you a lot more about what needs to be done, especially in regards to things like using the BIOS for initial low level setup.  There were a lot of tutorials on writing boot loaders at least, and they were enough for me to figure out x86 assembly well enough to get one working in Bochs.  I did have prior experience with MIPS assembly, but if you know anything about x86 assembly languages it would probably be easy enough.

Thanks Telgin, i shall.

Thanks, Fox News, I needed a laugh this week.

Explanation of GitHub for morons by morons

That's a surprisingly good description, given how the media portrayed Sergey Aleynikov. Yes, it's called subversion. That doesn't mean it's subversive.

..."reposotory"...wow 0_o

Anyhoo: Visual Studio 2013 (VS12) RC has been released. It's actually...pretty neat.

They finally have full cmath support (no longer will I see warnings over doing value != value when checking for NaN in UnitTest11), and fixed a few annoying bugs. It also means multiple category support for Visual Studio is in and all my tests are green.

Of course other annoying bugs are still there (Note to Microsoft: Fix your Variadic Macros!).

As a side note I'm thinking of throwing together a simple ReST API to allow me to update the build status of my projects on my website for Windows. Travis CI takes care of this on Linux, but whilst *I* know they're green since it's a managed by my localhost jenkins instance, I need some way to let the rest of the world know without spending $20 a month renting a server...

Thy understand it better than I do. Github is magic to me.

In C++, can I use structs as part of a class? Also, can a function return std::string strings?

In C++, can I use structs as part of a class? Also, can a function return std::string strings?

Structs are the exact same things as classes, except that every member/method is public by default, so yes.

And yes, a function can return any object (including std::string).

Okay thank you. Is there some sort of Bay12 (or other) programming IRC that I can go to to talk to programming people? Asking for help in a forum thread and waiting for an answer is not ideal (although people do respond quite quickly).

[Skyrunner]

I hang around #bay12lb @ irc.darkmyst.net most nights. Does that count? A bunch of other programmy people hang out there too.

How do I make a loop in C++ where a condition is that two strings are equal or unequal?

How do I make a loop in C++ where a condition is that two strings are equal or unequal?

The usual == and != work just fine with strings.

[Telgin]

Just to clarify, that's if you use the string class.  If you're using C style strings which are just character arrays, you should use the strcmp standard library function instead.

So, assuming you're not using C style strings and are using a while loop, something like this:

Code: [Select]

// Initialize these however you want
string first;
string second;

while (first != second) {
    // Do something
}

I'd highly advise using the string classes over raw character arrays wherever possible.
