How to read space separated numbers from console?

Question

I\'m trying to do a simple task of reading space separated numbers from console into a vector, but I\'m not getting how to do this properly.

Answer 1

To elaborate on jonsca's answer, here is one possibility, assuming that the user faithfully enters valid integers:

string input;
getline(cin, input);

istringstream parser(input);
vector numbers;

numbers.insert(numbers.begin(),
               istream_iterator(parser), istream_iterator());

This will correctly read and parse a valid line of integers from cin. Note that this is using the free function getline, which works with std::strings, and not istream::getline, which works with C-style strings.
