Library Management system implementation in CPP(C++)

      Library management system implementation could be a great assignment/project to polish many different concepts in C++. Here we have implemented the library management using structures like linked lists but in a two-dimensional manner. This does not use any database, but the concepts can be extended to a database instead. This implementation is perfect for college/university assignments, and personal project purposes.      This program in C++ uses many different concepts of Programming such as - Object-oriented programming, Linked list, Pointers, Complex data structures etc.      The problem statement for this Program may be -  " In a library, for each book book-id, serial number (denotes copy number of a book), title, author, publisher and price are stored.
