    copied!<p>To access catridgeClass attributes, you will need a catridgeClass object.</p> <p>First, you need to correct your class to have public attributes.</p> <pre><code>class catridgeClass:public game_list { public: string N_bits; bool is_import; }; class anotherClass: public game_list { public: string other_member; }; </code></pre> <p>Than you need to get a catridgeClass object from the caller function:</p> <pre><code>int main() { std::vector&lt;game_list *&gt; games; games.push_back(new catridgeClass); games.push_back(new anotherClass); for(int i=0; i&lt;games.size(); i++) { //You will need to get a catridgeClass object to access it's members. catridgeClass *catridge_ptr = dynamic_cast&lt;catridgeClass *&gt;(games[i]); //Or to access anotherClass. anotherClass *another_ptr = dynamic_cast&lt;anotherClass*&gt;(games[i]); //If the conversion is not possible, dynamic_cast will return a null pointer if(catridgeClass != NULL) std::cout &lt;&lt; catridge-&gt;N_bits &lt;&lt; std::endln; if(anotherClass != NULL) std::cout &lt;&lt; anotherClass-&gt;other_member &lt;&lt; std::endln; } //And of course, you need to avoid a memory leak for(int i=0; i&lt;games.size(); i++) delete games[i] return 0; } </code></pre> <p>Keep in mind that it's not a desired design. If you are trying to use polimorphism, is because all that classes share common behaviours. A better approach would be to use <a href="http://www.tutorialspoint.com/cplusplus/cpp_interfaces.htm" rel="nofollow">interfaces</a>.</p>
