In a stack, what will be the output of popping an element from an empty stack?

Step 1: Understand what a stack is. A stack is a data structure that stores items in a last-in, first-out (LIFO) manner.
Step 2: Know what 'popping' means. Popping an element means removing the top item from the stack.
Step 3: Recognize what an empty stack is. An empty stack has no items in it.
Step 4: Consider what happens when you try to pop from an empty stack. Since there are no items to remove, the operation cannot be completed.
Step 5: Conclude that trying to pop from an empty stack usually results in an error or an exception.
