Modify the booklist program (from the lecture notes) by adding delet and insert operations into the BookList class. The insert method should be based on a compareTo() method in the Book class that determines if one book title comes before another alphabetically. The insert method will maintain the BookList in alphabetical order. Exercise various insertion and deletion operations, using the code below for your main program: //lib.cpp #include pch.h #include using namespace std; #include "BookList.h" int main(int argc, char* argv[]) { //-------------------------------------------------------------- // Creates a BookList object, adds several books to the list, // then prints them. //-------------------------------------------------------------- char list[LIST_LEN]; BookList *books = new BookList(); books->insert (new Book("F Title") ); books->insert (new Book("D Title")); books->insert (new Book("G Title")); books->insert (new Book("A Title")); books->insert (new Book("E Title")); books->insert (new Book("H Title")); cout << "After inserts: ; cout << books->getBookList(list) << endl;; books->delet (new Book("A Title")); books->delet (new Book("H Title")); books->delet (new Book("G Title")); books->delet (new Book("E Title")); cout << "After deletes: "; cout << books->getBookList(list) << endl;; books->insert (new Book("A Title")); books->insert (new Book("E Title")); books->insert (new Book("H Title")); books->insert (new Book("G Title")); cout << "After 2nd inserts: ; cout << books->getBookList(list) << endl;; return 0; }
