Assigment HELP.. stuck & confused..

[brokenbndgedoll]

I have everything able to compile, but I have to add a few things and I am not sure what to do. Any suggestions or ideas would be GREATLY appreciated cause i am pretty clueless at this point.
THANKS!!
Write a function that returns the info of the n'th element of the linked list. If no such element exists, terminate the program.

Write a function that deletes the n'th element in the linked list. If no such element exists, output an appropriate message.
