quick question

C++.

I have an array of strings.
I want to read into this from cin until there is nothing left in the buffer.

i.e. input = "hello my name is anon"

i want the equivalent of

for(int i = 0; i < 5; i++)
    cin >> arrayName[i];

for any number of words

is there some sort of flag i can use?

vector<string> poo;
copy(istream_iterator<string>(cin), istream_iterator<string>(), back_inserter(poo));
