Answer 1

You can use getline with character delimiter.

istream& std::getline (istream& is, string& str, char delim);

Something like:

std::replace_if(s.begin(), s.end(), isColon, ';');
istringstream iss(s);
string temp;
int words = 0;
while (std::getline(iss,temp,';') {
  ++words;
}

And the predicate:

bool isColon (char c) { return (c == ';'); }
