Dear all, The only reason I posted the whole code was to give one the chance to run the program and see in practice the problem. But I guess that is too much. Anyway, The implementation of the two functions is: [code] //It returns the member. 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->association_list[index]->linked_member(); searching=false; } else index++; else index++; if (searching && (index == LIST_SIZE)) { searching=false; } } return member; } [/code] [code] //it returns the book template Book* AssociationList::get_book(Member* member) { Book* book=0; bool searching=true; int index=0; while(searching) { if (this->association_list[index]) if (this->association_list[index]->linked_member()==member) { book=this->association_list[index]->linked_book(); searching=false; } else index++; else index++; if (searching && (index == LIST_SIZE)) { searching = false; } } return book; } [/code] The template file that I use to display the books is: [code] template void List::displayElement(char* type) { if (num_elements == 0) cout<<"No "<num_elements; element++) { cout<<'\n'; this->element_list[element]->display(association_list.get_member(element_list[element])); } } [/code] But it does not work for Members. I've tried to use the recommendations you've told me but it seems not to work. The program works ok, when I call the functions: book1.addElement("Books"); and book1.displayElement("Books"); to add a book and to display them respectively. But when I use the : member1.addElement("Member"); and member1.displayElement("Member"); it dispalys the problem: The compiler complains at the point: this->element_list[element]->display(association_list.get_member(element_list[element])); saying that : get_member: cannot convert parameter one from Class Member* to class Book*. Can you correct any mistakes or suggest any solutions? Please if you make any suggestion adjust them to my code, if possible. Best Regards, grscot

Below the message editing area you will see a Formatting bar. You need to select all of your code and then click on "pre" and "code" to make it readable. Untill you start doing that your code examples are useless. Also short to the point snippets of code are far better than long winded examples.

...however, you will have to turn your less than and greater than into HTML escapes, and avoid any smiley combination... unless things changed since I last tried to post code

The Formatting bar has options for this too. ie. < and > Neville Franks, Author of ED for Windows. www.getsoft.com Make money with our new Affilate program
