Stack

• std::stack (STL Stack class)
  The STL (Standard Template Library) provides a generic and efficient implementation of the stack data structure through the std::stack class template.
• Stack C++
  A stack is an abstract data type (ADT) that follows the Last In, First Out (LIFO) principle. It is a collection of elements with two primary operations: push and pop. Elements can only be inserted (pushed) and removed (popped) from the top of the stack.
