We have to develop fully running system with friendly user interface to be used by nonprofessionals. We must use only files (mostly binary files) and C/C++ (C++ preferred) program code. No database system is allowed. In this project, we aim to create an online education platform. We will establish a site for both those who want to learn something and those who want to teach. 3 classes for Instructors, Learners, Courses. Initially, 2 options will be offered for profile selection. 1) Instructor 2) Learner - What we expect from the "Instructor"?
