C++ split string

Question

I am trying to split a string using spaces as a delimiter. I would like to store each token in an array or vector.

I have tried.

    string tempInput         


        

Answer 1

Notice that it’s much easier just to use copy:

vector tokens;
copy(istream_iterator(cin),
     istream_iterator(),
     back_inserter(tokens));

As for why your code doesn’t work: you’re reusing tempInput. Don’t do that. Furthermore, you’re first reading a single word from cin, not the whole string. That’s why only a single word is put into the stringstream.
