More templates problems

[grscot]

Dear all,I'm really sorry for asking again about the same thing, but I don't really undersatnd what's going on with the templates. I've tried to use the template R* get_member(P* pArg) as adviced, but it seems that my program is more complicated. So, I think I have to submit you a significant part of my code to give me an extra help (and final one I hope ) to overcome this awful template obstacle. AssociationList.h template class AssociationList { public: //It initialises all slots in the associationlist array to zero. AssociationList(); /* It searches the associationlist, if book is found then returns the member that is connected with.*/ //Member* get_member(Book* book); /* It searches the associationlist, if member is found then returns the book that is connected with.*/ //Book* get_book(Member* member); template R* get_member(P* pArg); /* Checks that book/member not already linked creates association if objects are free to link returns whether or not link was valid */ bool link(Book* book,Member* member); /* Checks that book and member are linked deletes association if they are linked returns whether or not unlinking was valid */ bool unlink(Book* book,Member* member); private: Association* association_list[LIST_SIZE]; }; AssociationList.cpp template AssociationList::AssociationList() { cout<<"AssociationList constructor called\n"; int index; for(index=0; indexassociation_list[index]=0; } template R* AssociationList::get_member(P* pArg) { R* member=0; bool searching=true; int index=0; while(searching) { if (this->association_list[index]) if (this->association_list[index]->linked_book()==book) { member=this->association_list[index]->linked_member(); searching=false; } else index++; else index++; if (searching && (index == LIST_SIZE)) { searching=false; } } return member; } //template //Member* AssociationList::get_member(Book* book) /*Member* AssociationList::get_member(Book* book) { Member* member=0; bool searching=true; int index=0; while(searching) { if (this->association_list[index]) if (this->association_list[index]->linked_book()==book) { member=this->asso

What is wrong with (.h) Member* get_member(Book* book); (.cpp) template<class Book,class Member> Member* AssociationList::get_member(Book* book) { ... } ?
