i ve already sent the total code................... look i have class like: class Class {
} void func(){ std::list<Class> l; l.push_back(Class(0)); l.push_back(Class(0)); func(&l); } i want to pass that list to different function but iits not working............. like void func2(list<Class> &l){ list<class>::iterator p=l.begin(); the element of the Class can not be accessed............................plz help }//is not working.................. ________________________________ From: Tyler Littlefield <ty...@tysdomain.com> To: c-prog@yahoogroups.com Sent: Tuesday, April 7, 2009 5:18:58 AM Subject: Re: [c-prog] [C++: passing a list to a function --mod] plz help me..................................its urgent............. what about it.
