Intro – Student Management System
A Student Management System (SMS) is a software which is used for manage the student data, such as registration, attendance, grades, and other related information. Implementing a basic SMS in C++ involves designing data structures to store student records, implementing functionalities to add, delete, modify, and display student information and handling user interactions through a command line interfaces.
Key Features of Project
- Student Record:
- Each student record typically includes attributes such as student ID, name, age, gender, course enrolled, grades, attendance, etc.
- Functionalities:
- Add Student: Allows adding a new student record to the system.
- Delete Student: Deletes an existing student record based on student ID.
- Update Student: Modifies information (e.g., grades, attendance) of an existing student.
- Search Student: Searches for a student record based on student ID or name.
- Display All Students: Displays all student records stored in the system.
- Data Management:
- Utilizes data structures like arrays, linked lists, or dynamic arrays (vectors) to store and manage student records.
- Implements file handling for data persistence (optional).
