c++ program ProjectsStudents are required to show OOP concepts while exercising thefollowing projects. Students are supposed to implement as many asthey can the concepts of OOP.
Student Information SystemThis is also a simple project, make person as the base class,teacher and student should be its derived classes. Project shouldimplement which course student has taken from which teacher andwhat were the grades of student in that subject.
having introduction, class diagram and the implementation(code). create student. txt file like this where's student informationstore.
and create multiple classes like this. also createnteacher class.
improve this program...
