Code Review: Library Information System

Compiler or Tool: Turbo C

Programming Language: C++

User Interface Type: CUI [Character User Interface]

Description:

This Library Information System allows library staff to maintain their customer-n-books database with details such as new book or customer entry, issuing or returning book, listing all members or books etc. Even though the system is medium size it teaches how to code simple file handling support system with intuitive menu in C++ language.

The System contains 3 structures and 1 class, library class with following properties and methods:

The main() function presents main menu and becomes single point entry and exit code. The main() function call graph is as follows:

The menu presented by this main() function is as follows:

 

The system uses basic commands to arrange data on screen and 3+1 classes are used to manage the system. To study the code includes how files are read and write with very fancy menu.

Total code lines for this system are 1122 lines [approximately]. It is a most suitably called as mini project in C++ language.
