 1 | # librarymanagementsystem
 2 | In this article, we will discuss the approach to create an E-Library Management System where the user has the following options:
 3 | 
 4 | 1. Add book information.
 5 | 2. Display book information.
 6 | 3. To list all books of a given author.
 7 | 4. To list the count of books in the library.
 8 | Functionalities Required:
 9 | 
10 | If the user tries to add a book then the user must have to provide the below specific Information about the book as:
11 | 1. Enter Book Name:
12 | 2. Enter Author Name:
13 | 3. Enter Pages:
14 | 4. Enter Price:
15 | When the user tries to display all books of a particular author then the user must have to enter the name of the author:
16 | 1. Enter the author name:
17 | The E-Library management System must be also capable of counting all the books available in the library.
18 | Below is the program to implement the E-Library Management System
