Is it possible to change the delimiter of a stringstream? For example,

#include<sstream>
#include<string>

int main(){
std::string s;
std::stringstream ss("A B C");
ss >> s;
}

Then s is "A". Is it possible to make s be "A B C"?

Thanks, I know I can do it other way. But I still want to know whether I can do it within stringstream or not.

Well the following will work:

(Toggle Plain Text)

#include<sstream>
#include<string>

int main(){
std::string s;
std::stringstream ss("A B C");
s = ss.str();
}

Is that want you're looking for?

No he is looking for a way to split "A-B-C" or "A:B:C" using string streams.

Eoin · Dec 26th, 2006, 2:25 PM

Not sure if that is what he wants, the post is very unclear.

Any-hoo this link might be useful: skipws / noskipws

No, I want to see if there is a way to do something like getline(x,y,delim) using the operator >>. It's something like std::skipws but std::skipws is only about the first white space but not the delimiter.

After some googling and searching in my books, it seems that there is no way to do it just by using the operator >> . Anyone could confirm this?

Yeah, I now see why it was unclear as I should write "A B C \n" instead. So instead of stopping at the first white space, is it possible to change the stream to make it stop at \n.

I think stringstream extends iostream, so you should be able to use the getline function, which allows you to set a delimiter.
