    Splitting strings into words.

    yes i could probablly sit down and write some ugly loop to split a string into individual words, however im interested in knowing if there is a more elegent way to do what i want.

    string s1 = "hello my name is bob";
    vector<string> v1;

    the end result im looking for is something like
    v1[0] = "hello"; v1[1] = "my"; v1[...] = ...;

    can i take this and dump it into a vector of strings, or pipeing it somehow like s1 >> s2; or anything like that. ya i know it wont work but im just kinda pulling ideas out of my ass. im a perl monk and i miss my split and foreach functions =P

    Code:
        string str = "hello my name is Codeplug";
        string word;
        istringstream is(str);
        vector<string> sv;
    
        while (is >> word)
            sv.push_back(word);
    This will parse on spaces, if you want to do anthing more fancy, you will have to do it yourself or you could use C-string lib function strtok(). And there are all the examples from Rod's post.

    istringstream

    ok, im liking this istringstream thing, what shall i include. its $$$$$ing because "is" uses undefined class basic_istrginstream bla bla bla.

    Talking yep, thx

    ya that deffinetly god it, thanks alot. no more ugly split functions for every program i write w00t! i was trying to include stuff like istringstream and stringstream. never thought of sstream, and of course the msft help phile is most unhelpful. we recently decided that the msft help file was based on recursion because you need to know the answer to your question to find it. lol.
