Students Management System

Question

Is there any better approach to solve it? The actual question is like c++ code to form this system with all cases like add,delete,sort, display, results, search, update, duplicate, and copy. I know this code will not run on Sololearn. This is my summer project and i don't want any loopholes in it. I will be grateful to you.
(Note: I wrote this code on DEV C++, Vers. 5.11)
