Student Information System C++ Project

Student Information System Project

Dear Students, Today in C++ Programming Tutorial we will learn How to make a a simple c++ project Student Information System Using Linked list. It is a simple example of a complete system with the functionality of add record, search record, Update record and delete record using linked list. Previously we shared Student Management System Project in C++. If You understand basic CRUD (Create, Read, Update and Delete) functionality it would be easy for You to create any Management System using this functionality.

Concepts used in C++ Project

Student Information System Project uses the concept of following topics:

• Pointers
• Loops
• Functions
• Linked List
• If Else

Major Functions in C++ Project

Student Information System C++ Project has 5 major function in menu

• Add New record
• Search a record
• Modify a record
• Delete a record
• Exit

How it Works

The menu is handled by if else statement. While adding a new record, if any node already exist then new node is connected with it otherwise a new node is created. While searching a node, a pointer searches all the pointers of linked lists to match the required data from start to end. While Modification the data part of the linked list is overwritten with new data and in case of Deletion, the pointers before and after of the node which we need to delete are connected with each other.
