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

Step 1: Understand what a stack is. A stack is a data structure that follows the Last In, First Out (LIFO) principle.
Step 2: Know what 'popping' means. Popping an element means removing the top element from the stack.
Step 3: Recognize what an empty stack is. An empty stack has no elements in it.
Step 4: Consider what happens when you try to pop from an empty stack. Since there are no elements to remove, the operation cannot be completed.
Step 5: Learn that trying to pop from an empty stack usually results in an error or exception. This is a way for the program to tell you that the action is not allowed.

Stack Data Structure – A stack is a linear data structure that follows the Last In First Out (LIFO) principle, where elements are added and removed from the top.
Exception Handling – Understanding how operations on data structures can lead to exceptions when preconditions (like non-empty stacks) are not met.
