In a stack, if a user tries to remove an element from an empty stack it is called underflow.
<h3>What is underflow?</h3>
When we attempt to pop (remove) anything off the stack but there is nothing there to remove, stack underflow occurs. The computer will kind of sound an alert as a result of what we taught it to do, which is impossible.
The options are:
1) Underflow
2) Empty collection
3) Overflow
4) Garbage collection
As we know,
When an item is requested from the stack but the stack is empty, an error situation arises.
Thus, in a stack, if a user tries to remove an element from an empty stack it is called underflow.

Pointer arithmetic allows us to perform integer additions or subtractions for the operation in pointer.
Answer:
By keeping track of file links and deleting them along with the files
Explanation:
when different users create different files with the same name, and one tries to open one of the files, the first file that is found on the VTOC of the disk will be opened. These problems can be avoided by tracking of all links to a file, and whenever there is a need to delete a file, the link to the file as well should be deleted.
