I think boost is a bit of an overkill here, when my function does precisely what is needed and has the added benefit of the separator token being a std::string, not a single char. With that said, he wanted it split into an "array", not just printed to stdout, so you'll need to store the values in an array-like container, which std::vector is.

I am sorry cerulean, but i think you (and maybe the others) didnt understand the code.

1) i think you have no idea the code intern looks like!

my function has the benifit to every kind of predecate!!!!
boost::is_any_of(""); is only one example
you could also use std::eqal and many more
you can implement every other kind of predecate yourself!!!
or to work on non-char delimters you also could use boost::tokenizer

the function split gets a reference to the result container! so the vector<std::string> result holts the result, like your did. and u also could use EVERY other container which can hold a type convertable to the string!
sorry the std::copy function is just an additional output. here is the code again!

(Toggle Plain Text)

#include<string>
#include<vector>
#include<boost/algorithm/string.hpp>
int main() {
	std::vector<std::string> res;
	boost::split(res,"hallo-this-is-a-string",boost::is_any_of("-"));
}

I am sorry but if somebody doesnt understand some code he should't start talking about its correctness....

do u really think my solution is complicated? what does that mean?
using a function that exactly does what somebody asks for is complicated?
of is the handling of
function(param1,param2.param3) too complicated?
i think u really didnt understand! the author doesnt need to do anything but use the function.. thats really not a conplicated thing...
whats your prob with templates ? I think its one of the most powerfull things in c++ and you just dislike them or something.... I am sorry but this solutions is fast,optimized ( written by very good designers and coders) and really easy and intuitive to use.... sorry but i really didnt get your point...
but if u think this whole thing is to complicated and a huge overhead then u also should stop using the string,vector,.... the whole stl... and you should also programm in c instead of c++...

Get real.

I am ... but if you think it wont be like that please tell me why u think that !
its already decided that some boost thinkgs are in the next c++ standart and the string algo and regex things are candidates ... so what do you think about this.

Yes because I shutter and close my eyes every time I see a template

I hate them so much I refuse to code them myself -- I'll use those from STL because I don't have to actually read them to use them. The boost library examples you posted is totally beyond my comprehension.

Regardless. Boost is a library which I very much love (especially Boost:

ython), but for something like this I don't think it's needed. It is a large library.

That was in reference to Ancient Dragon's sample, not yours. I'm quite aware of what boost::split does

I assumed, maybe wrongly, that the op had enough sense to figure that part out for himself.

Heh, I was just referring to the following:

And thought that you meant using a vector.

ok, but i wasnt able to figure out that that didnt meant me.
well the boost libs are sometimes big, and but you are able to include just a few parts. but i think the perfomance and overhead-argument is understandable, as u can see by the size of the binary. but sometimes this resources are not the limiting fact so its always good to know about the libs that are usable, but i have to admit thats its never wrong to write an own solution if a lib would be an overhead. and sometimes u have to do that and in other cases its just like there is just a little overhead, or you have to focus on another implementation level and so u could/should use a lib..

greets
