Peek - it will show the element on the top of Stack(without removing it).If we try to perform a pop operation on an empty Stack, then it is said to be Stack Underflow condition. Elements are always removed from the top of Stack. Pop - it specifies removing an element from the Stack.If we try to insert an element when the Stack is full, then it is said to be Stack Overflow condition Push - it specifies adding an element to the Stack.Here we will define three operations on Stack, Since it allows insertion and deletion from only one end and the element to be inserted last will be the element to be deleted first, hence it is called Last in First Out data structure (LIFO). If we want to remove an element from the Stack, we can only remove the top elementįrom Stack. C/C++ Program for Check whether a given Binary Tree is Complete or not. C/C++ Program for Implement Queue using Stacks. C/C++ Program for Linked List Implementation of Queue. Queue: C/C++ Program for Queue Introduction and Array Implementation. New elements are added at the top of Stack. C/C++ Program for Design a stack with operations on middle element. What is Stack? A Stack is a linear data structure which allows adding and removing of elements in a particular order. We will discuss various I/O operations on these data structures and their implementation using another data structure, a Linked List. Introduction In this article, we will discuss two data structures - Stack and Queue.
