📘 Student Report Card Management System (C++)
A simple console-based Student Report Card Management System built using Object-Oriented Programming (OOP) in C++. The system allows adding, viewing, and searching student records. All data is stored in a text file (students.txt) for persistence.

File Description
Student_Management_System Main C++ source code containing the full implementation
🎯 Features
Add new student details
Calculate total marks, percentage, and grade
Save records in a file permanently
View all existing records
Search a student by roll number
Simple menu-driven system
Fully implemented using OOP + File Handling
🗂️ How the System Works ➤ 1. Add Student
The program asks for:
Roll Number
Name
Marks in Maths, Physics, Chemistry
It automatically calculates:
Total Marks
Percentage
Grade (A, B, C, D, F)
Then it writes everything into students.txt.
➤ 2. View All Students
Displays:
Roll No
Name
Individual subject marks
Total marks
Percentage
Grade
Records are read directly from the file.
➤ 3. Search Student
Enter a roll number → program displays the matching student’s details.
🧮 Grade Calculation Logic
90% and above → A
75% - 89% → B
60% - 74% → C
40% - 59% → D
Below 40% → F
🛠️ Compilation & Execution ✔ Windows (MinGW) g++ -o student "Student_Management_System" student.exe
✔ Linux / macOS g++ -o student "Student_Management_System" ./student
📄 Data Storage Format
Each record is stored in this format:
rollNo name maths physics chemistry total percentage grade
Example:
97 Manu 90 90 90 270 90.00 A
