    strtok() can be used in c++ the same way its used in c
    just include <cstring>

    If you mean with C style strings then you can just use strtok in <cstring>, if you mean with the string class then you can do something like this
    Code:
    #include <iostream>
    #include <string>
    
    string bad_char = " ";
    
    string next_token(string& s, string::size_type& pos)
    {
      size_t begin = s.find_first_not_of(bad_char, pos);
      size_t end = s.find_first_of(bad_char, begin);
    
      pos = end;
    
      if (begin == string::npos)
      {
        return string();
      }
      else if (end == string::npos)
      {
        return s.substr(begin);
      }
      else
      {
        return s.substr (begin, end - begin);
      }
    }
    
    int main()
    {
      string::size_type pos = 0;
      string s = "Breaking up a string";
      string t;
    
      while (!(t = next_token(s, pos)).empty())
      {
        cout<< t <<endl;
      }
    }
