two error come of (strcpy was not declare in this scope)
would any one show me, hw to remove this error, ... plz
Project Title: Student Record & Registration using Linked list
Description: This project is a Linked List application. If you would like to refresh you knowledge about linked list, you may read this article: Linked List. The project considers an engineering university having three departments: Electrical, Mechanical and Comptuer System Engineering(CSE). The university considers Metric(O-level) , FSc(A-level) and entry test marks for registering a student and calculate an aggregate based on a specific criteria. The project finds in which dept. a student should be registered and store its record(temporarily) using linked list. Note that this Linked list implementation just serves as a starting point. You may modify it (like adding other departments in the university and changing admission criteria) or extend it (for instance, writing the student records to a text file for later retrievel).
