// gives you the first token, if it is NULL, all the characters in the string were from delimeters.

You can also do the same thing in this way too.
vector split( string s, string del = " ")
{ char *word, *buf, *delim;
vector res;
delim = strdup(del.c_str());
buf = strdup(s.c_str());
for (word = strtok(buf, delim); word; word = strtok(0, delim))
res.push_back(string(word));
free(buf);
free(delim);
return res;
}
strdup can also be used instead of strcpy, but you should never forget to free the memory, though most of time not necessary in contests.
