Consider...

Token_value get_token()
{
  char ch=0;

    <snip>

  default:
    if(isalpha(ch)) {
      string_value = ch;
      while(cin.get(ch) && isalnum(ch))

        // was ??
        // string_value.push_back(ch);
        // now !!
        string_value += ch;

      cin.putback(ch);
      return curr_tok=NAME;
    }
    error("bad token");
    return curr_tok = PRINT;
  }
}

/
*Yields...

(2+3)*4+3*2
26

Is that what you wanted??
