Student Management System

This is a student management system implemented in C++ that provides functionalities to manage student data. The system allows you to add, view, search, and display students based on specific criteria like the highest and lowest average grades.

Features

1. Add New Student: Allows users to input and add new students to the system with details such as student code, full name, date of birth, and average grade.
2. Display All Students: Displays the list of all students with their details.
3. Search by Student Code: Search for a student by their unique student code.
4. Display Students with the Highest Average Grade: Displays the student(s) with the highest average grade.
5. Display Students with the Lowest Average Grade: Displays the student(s) with the lowest average grade.
6. Data Persistence: Student information is saved and loaded from a file (danhsachsinhvien.txt), ensuring data is preserved even after the program is closed.

How to Use

1. Run the program:

   • PLEASE RUN THE ONLY .EXE FILE

2. The following options will be available:

   • Add new student to the list: Enter student details like code, full name, date of birth, and average grade.
   • Display all students: View a list of all students in the system.
   • Search for a student by student code: Search for a specific student by entering their student code.
   • Display student with the highest average grade: View the student(s) with the highest grade.
   • Display student with the lowest average grade: View the student(s) with the lowest grade.
   • Exit: Exit the application.

3. Student data will be saved in the file danhsachsinhvien.txt, ensuring data persistence.

File Format

The file danhsachsinhvien.txt stores the student information in the following format:

• The first line contains the number of students in the list.
• Each student’s information is stored in the following order:
  • Student Code
  • Full Name
  • Date of Birth (dd/mm/yyyy)
  • Average Grade
• Do not change the danhsachsinhvien.txt file

Code Explanation

1. Standardization of Input: The system ensures that the name is capitalized properly and that the date format is consistent (dd/mm/yyyy).
2. Validation: The program validates the student code, date of birth, and average grade to ensure correctness.
3. Leap Year Check: The system accounts for leap years when checking the validity of a student's date of birth.

Acknowledgments

• The system is built using C++ Standard Library (STL) and basic file handling.
• Special thanks to the creators of C++ documentation and tutorials.

For Examiner

• Thank you, teacher, for reviewing my code. I have added detailed notes for each function, method, and feature in the code. I hope you can provide feedback and help improve my code so that I can perform better in the future.

THIS PROGRAM CAN NOT RUN WITH A LIST OF 100000 Students or above because i use liner search for searching(to lazy to overload operators, may be i'll do it to apply binary_search or something faster on this program but i think there won't be any school that have more than 10000 studens : DDDDD)
