Greetings! Today, we'll unveil the Stack data structure in C++, an essential part of your programming toolkit. A stack operates much like a stack of dishes: you place a new dish on top (Last In) and you remove the top dish (First Out). This Last-In, First-Out (LIFO) method illustrates the stack. In C++, we utilize the Standard Template Library (STL) stack to manage these operations with ease. This lesson will enlighten you about the stack data structure, various operations, and their practical applications in C++. Are you ready to dive in?

A stack is a structured storehouse that enables push (to add items) and pop (to remove items) operations. It's similar to a stack of plates in a cafeteria where plates are added (pushed) and removed (popped) only from the top, demonstrating a Last-In, First-Out (LIFO) operation.

To implement a stack, C++ offers a dedicated container known as stack in the STL. To add an element to the top of the stack, we employ the push() method. The pop() method, on the other hand, removes the top element, carrying out the removal process. Here’s a look at this operations in code:
