Curriculum Design-Library information Management system

Introduction: Curriculum Design-Bank savings system--"here

Library information Management system includes: Login number, title, author name, classification number, publishing unit, publication time, Price and so on. Try to design a library information management system, so that it can provide the following functions:

(1) The system works in menu mode
(2) Library information entry function (student information file saving)---input
(3) Book information browsing function---output
(4) Query, sorting function
Query by login number
Search by Title

(5) Deletion and modification of book information
