    What is a stack?

  • #2
    A stack is a conceptual structure consisting of a set of homogeneous elements and is based on the principle of last in first out (LIFO). It is a commonly used abstract data type with two major operations, namely, push and pop. Push and pop are carried out on the topmost element, which is the item most recently added to the stack. The push operation adds an element to the stack while the pop operation removes an element from the top position. The stack concept is used in programming and memory organization in computers.

      A stack is a container of objects that are inserted and removed according to the last-in-first-out (LIFO) principle. In the pushdown stacks only two operations are allowed: push the item into the stack, and pop the item out of the stack. A stack is a limited access data structure - elements can be added and removed from the stack only at the top. push adds an item to the top of the stack, pop removes the item from the top. A helpful analogy is to think of a stack of books; you can remove only the top book, also you can add a new book on the top.

        A Stack is a data structure which is used to store data in a particular order. Two operations that can be performed on a Stack are: Push operation which inserts an element into the stack. Pop operation which removes the last element that was added into the stack. It follows Last In First Out(LIFO) Order.
