6. School Management System in C++

School Management System in C++ is also a good idea for beginners. This project involves designing functions for student enrollment, attendance tracking, and grade management. Learn object-oriented programming principles to model real-world entities such as students, teachers, and courses. Through this project, you’ll refine your C++ proficiency and gain an understanding of the complexities of school management.
