Get words of a sentence into a vector

How does one go about having a user input a sentence, and the program picking the words apart and putting each word into a vector. I've tried something like this, but it ends up stalling:

vector<string> sentence;
string nextWord = "notyetdefined";

cout << "Type your sentence:" << endl;
while (nextWord != "" && nextWord != "\n") {
    cin >> nextWord;
    sentence.push_back(nextWord);
}

I've also tried detecting for a period at the end of the sentence which works, but is annoying that the user would have to put a period everytime, because they might often forget, resulting in an endless loop that I'm not sure how to deal with.

EDIT: Managed to find a fix by using this question: Split a string in C++? that was suggested to me in the comments.

@Pradhan, I'm surprised it even compiles at all – Alejandro Jul 06 '15 at 15:38

When do you want it to end? If the user types **Roses are red. Violets\n are blue** then what result do you want? – Beta Jul 06 '15 at 15:39
'twas a mistype guys, i didn't copy-paste this, so human error is possible. – Jacob Oaks Jul 06 '15 at 15:39
Maybe instead use getline(cin, ...) and then split the line into tokens? – KABoissonneault Jul 06 '15 at 15:39
@Beta Whenever they press enter, or whenever there is a newline. In your sentence, right after Violets. – Jacob Oaks Jul 06 '15 at 15:40

Then I'd use `getline` and `stringstream`. – Beta Jul 06 '15 at 15:49
