17-Nov-2023When a stack is accessed while it's already empty, attempting to pop an element from an empty stack typically results in an exception. In many programming languages, the exception thrown in this scenario is commonly referred to as an "EmptyStackException" or something similar. Here are examples from a few programming languages:
C# (using .NET framework):
Java:
Python (using a list as a stack):
In general, it's important to check whether the stack is empty before attempting to pop an element to avoid such exceptions. Most programming languages provide methods or functions to check if a stack is empty before performing pop operations.
