C++ Stack Data Structure: Complete Guide

In C++, the stack data structure is commonly implemented using containers, with std::stack being the most frequently used container. std::stack is a template class that serves as an adapter for implementing a Last In First Out (LIFO) data structure. It can be used to create a stack and perform operations such as push (to add an element), pop (to remove an element), and top (to access the top element). By default, std::stack uses std::deque as its underlying container, but other container types can also be specified.
