Student Management System using C++ With Source Code
Introduction :
This is a student record management system project, which enables you to create, read, modify, and delete student Records. This project is developed using the programming language C++.
Student Management system is a management information system for education to manage students’ data. It includes the idea of topics like structure, loops, arrays, if-else, switch, and so on. It helps the user to store student data and make changes to it such as Show, Update, Delete, and Search. The features of C++ programming language help here to manage data and apply logic to the programs.
