## Overview

This is a menu-driven C++ student-record application. Users enter through the console menus to add, find, display, modify, or delete records, and can request individual or class reports. Student records hold subject marks and derived percentage, grade, and CGPA; the database keeps up to 100 records in an in-memory array. The implementation is concentrated in one source file. The graph reflects that file and README; it does not imply persistence or other future-improvement features.

Main entry points: [`student.cpp`](https://github.com/uzaam07/student-management-system/blob/main/student.cpp) (StudentDatabase)
