This code by C to :

1- Create a sorted linked list using tenStudent array (copy from array into the linked list will be done).

2-Append an element to the end of a list

and Details in the picture:

>>>>>>>>>>>>>>>>>>>>>>>

I want to update the code to :

1- Delete the last element from a list.

2- Delete the nth element from a list.

The code:
