C++ project: Student Management System

Sharing is caring!

Create a student management system to store and manage student information in a school or educational institution. The system should allow users to add students, see student details, search for students, and execute basic activities such as updating and deleting student records.

Requirements

1. The system should have a user interface where users can interact with the program.
2. Users should be able to add new students by providing details such as student ID, name, age, grade, and contact information.
3. Users should be able to display a list of all students in the system, including their details.
4. The system should allow users to search for students based on various criteria, such as student ID, name, or grade.
5. Users should be able to update student information, such as their contact details or grade.
6. The system should provide the option to delete a student record from the system.
7. Implement basic input v

    return 0;
}

Optional Enhancements

1. Add a feature to calculate and display statistics, such as the average age or grade of all students.
2. Implement a feature to generate reports, such as a list of students in a specific grade or with a specific age range.
3. Include a feature to sort the student records based on different criteria, such as student ID or name.
4. Implement a user authentication system to differentiate between administrators and regular users, allowing administrators to perform administrative tasks such as adding or deleting student records.
