Step 4
That's a pretty nice linked list you got there! But let's test the dynamic nature of a
linked list. In arrays, if you want to delete an element, you either have to resize the array
and copy its contents back and forth, or swap some elements and ignore others. No fun either
way. So let's delete an element the linked list way--by calling Delete(). Don't worry, it's
already written for you.
- In lab12.c, uncomment the lines of code that prompt and get an id
number from the user to delete from the class list.
- In lab12.c, uncomment the lines of code that attempt to delete a student with
the entered id.
- Call PrintList() to verify that the list shrunk correctly.
Moving on to Step 5...
