add(Ta) and deleting(int i) taking on consideration to throw exception for duplicatio
 

Hi,
i'm working on assignment i did part of it and i need help in some functions which are : add(Ta) and remove(int i)// an exception is thrown when adding a duplicate entry or when deleting with an out of bound index i .
the instructor gave us the main class and he asked us to provide the missing classes and functions the are needed to make a main program to run correctly .
i'd like to help me in those two functions .or to guide me how to work on them
note: th assign3.h & assign3.cpp thos classes that i worked on them
Assignment3.cpp that's from the instructor.
