surely you meant to use a standard algorithm instead of writing a loop like a caveman

a mere mortal only really needs to know about lvalues and rvalues (and you can in fact pretty much ignore the later and still write functionnal c++ code, if slightly inefficient at times bc of superfluous copies) the other -values are basically just there to define all the subtleties of the behavior of rvalues and move semantics in the c++ standard and a mere mortal doesn't have to know all those intricacies to write c++ code lol if u use a single-vendor language where they dont need to go into that much standardization detail

i just python to do stuff and its real easy and i don't have to spend 12 hours debugging super vague errors and tedious pointer problems the only thing i can think of doing with c that might be vaguely interesting is calculating stuff really fast with a GPU but I don't have any problems where time is a huge factor. like i could make a fractal zoomer or something but it would only run on windows if u have a nvidia video card

hey programmers: i've been using this nifty Haxe thingy it's an offshoot of actionscript 2 which you'd think would be awful and there is some goofy syntax wangdiggery but on the whole the whole project seems really well thought out and a lot of the library support for it is surprisingly good you can write your code once using a library like openfl for graphics, and it'll target compile to C++/swf/html5/neko binaries and not some VM-y thing i've been having a fun  COMPUTER SCIENCE journey with it and it's features

Cocoa Crispies posted:lol but at the same time oh yeah this stuff is a whole mess of python w/ some compiled libraries, we're replacing one of the libraries for political reasons so i gotta re-implement the parts we touch, ive been keeping them in python when i can (and it is kind of nice for the old ego when my python is about 2x as fast as the library's c) but sometimes theres just no getting around it i ended up re-reimplementing the naive c version w/ a fancier algorithm w/ better complexity, but i switched to c++ b/c its not worth hacking up yet another stack/queue/map/etcetcetc thing in c when the stl's right there

its even worse because the program is actually quite a bit of c as in no objects no design thought no anything good boost looks scary, managing threads sounds lol

i'm no wizard but theres some pretty cool approaches to threading our your program that require very drastic/interesting architecture changes, like making a common 'task' base type and each thread in a pool is just handed a 'task' and told to make it go, then you break your poo poo into a nice service oriented communication driven model with events and clearly defined thread safe interfaces might as well just dehumanize self and face to erlang etc. at that point theres a buncha ways to do a thing

anyways read this: http://www.amazon.ca/C-Concurrency-Action-Practical-Multithreading/dp/1933988770 most of it is applicable to boost threads, since the c++11 threads were mainly designed by the maintainer of boost threads (the guy who wrote that book). big thing to know about is the new memory model if you're using c++11
