[Linked_List]Book

//Created: May 26th, 2015//Last Modified: July 2nd, 2015 Tue//Linear List "BookList", implemented in Linked List (1-way)//Linear List "BookArray", implemented in Dynamic Array//Note: On June 29th, 2015, encountered a problem that I feel hard to resolve; The problem is that, when two adjacent items in a linked list are to be swapped, the enumerator pointer moves, which caused a problem when a list like of 9 8 100 6 5 4 is to be sorted.//Note: On June 30th, 2015, the problem listed on June 29th, 2015 was resolved. The problem was how to locate the enumerator pointer. As swap moves this enumerator pointer, I added another pointer to be the preceder of the enumerator pointer. As this preceder won't involve the swap, it is stable all the time. Using this pointer to get next makes this process stable independent of swap#include <iostream>#include <string>#include <vector>#include <cstdlib>using namespace std;class Book{public:    Book();    Book(string name_par, int index_par);
