Answer to Question #255657 in C for Neil

Question

Create three structures using linked list: Student, University & Branch.

Student structure contains Name, Roll No & Branch ID [in which the student studies], University structure contains University ID & University Name) &

Branch structure contains Branch ID & Branch Name

Implement the following function to :-

• Display the list of students reading in IIT University.
• Display the student details who are reading at IIT University with branch CSE.
