Introduction In this lab, we will use class to design a library management system. In the library management system, we defined a class called Book to store all the information of a book, including name, number of pages, number of authors and author names. Also, since the books are stored by a linked list, there would a pointer next pointing to the next book. To simplify, we use a string without space to store the names of books and authors. For example, if a name is "Abc Def Ghi", we use "Abc_Def_Ghi" to represent it.
Tasks There are 5 tasks in book.cpp. Descriptions of tasks are provided below, instructions and some examples are also provided via comments in the skeleton codes. • Task 1: Constructor of a new book. In this part, all the information of a book including numPages, numAuthor, authorList, name, next will be initialized. Note that next would be initialized as nullptr in the constructor, and its value would be set in main.cpp after a book is constructed. Alao, remember to allocate memory for variable name, numAuthor, and each element in the array numAuthor. • Task 2: Destructor to delete an existing book. In this part, all the memory allocated previously in the constructor should be deallocated. Note that for an array (e.g., numAuthor), the array as a whole and each element in the array should be deallocated respectively.
