aJ said what is needed. My advice is avoid that ugly & unsafe strtok. You are using C++ so go ahead with std::string. You also can use Boost http://www.boost.org/doc/libs/1_43_0/libs/libraries.htm#String & http://www.boost.org/doc/libs/1_43_0/doc/html/string_algo.html . If you want a new string class, you may look at http://bstring.sourceforge.net/ .
