Student Management System

This is a C++ project that implements a Student Management System. It allows users to manage student records using a combination of a Binary Search Tree (BST) for efficient retrieval and a std::vector to store full student data.

Features

• Add new students.
• Display all students.
• Remove a student by year of enrollment.
• Retrieve and display details of a student by year of enrollment.

Files and Structure

The project is split into the following files for better readability and modularity:

Source Files

1. main.cpp:

   • Manages the main menu and program flow.
   • Calls the necessary functions to interact with the BST and the student records.

2. Student.h:

   • Defines the Student structure containing:
     • name: The name of the student.
     • year_of_enrollment: The year the student enrolled.
     • GPA: The student's Grade Point Average.

3. BST.h & BST.cpp:

   • Implements a Binary Search Tree for managing the year_of_enrollment.
   • Allows insertion, retrieval, and removal of nodes based on the year of enrollment.

4. StudentFunctions.h & StudentFunctions.cpp:

   • Implements functions to:
     • Add a new student.
     • Display all students.
     • Remove a student by year.
     • Retrieve details of a specific student by year.

Compilation Instructions

To compile and run the program, ensure all files are in the same directory and execute the following command in your terminal:

clang++ -std=c++17 -o StudentManagement main.cpp BST.cpp StudentFunctions.cpp

Alternatively, if you are using GCC:

g++ -std=c++17 -o StudentManagement main.cpp BST.cpp StudentFunctions.cpp

How to Run

1. After compiling, run the program with the following command:

   ./StudentManagement

2. Follow the on-screen menu to:

   • Add students.
   • Display the list of students.
   • Remove a student.
   • Retrieve a specific student's details by year of enrollment.

Example Interaction

Menu:

--- Student Management System ---
1. Add Student
2. Display Students
3. Remove Student
4. Retrieve Student
5. Exit
Enter your choice:

Sample Input and Output:

Adding Students:

Enter name: John Doe
Enter year of enrollment: 2020
Enter GPA: 3.5
Student added successfully.

Displaying Students:

Name: John Doe, Year: 2020, GPA: 3.5

Removing Students:

Enter the year of the student to remove: 2020
Student removed successfully.

Retrieving a Student:

Enter the year of enrollment to retrieve: 2020
Name: John Doe, Year: 2020, GPA: 3.5

Requirements

• C++17 or later.
• A C++ compiler like GCC or Clang.

Notes

• The Binary Search Tree is used to manage the year_of_enrollment for efficient retrieval and updates.
• The std::vector stores the full student details, ensuring all data is preserved and accessible.

Future Improvements

• Add error handling for invalid inputs.
• Support for updating student details.
• Enhance the display function to allow sorting by different fields.
