In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and. pop, which removes the most recently added element that was not yet removed.Click to see full answer. People also ask, what is stack with example?A Stack is a sequential organization of items in which the last element inserted is the first element removed. They are often referred to as LIFO, which stands for “last in first out.” • Examples: letter basket, stack of trays, stack of plates.Furthermore, how do you pop an element from a stack? Operations on Stack: push( x ) : insert element x at the top of stack. pop( ) : removes element from the top of stack. topElement ( ) : access the top element of stack. isEmpty ( ) : check whether the stack is empty or not. size ( ) : tells the current size of stack . Keeping this in view, what happens when you pop an empty stack? The Pop() method returns and removes elements from the top of the Stack. Calling the Pop() method on the empty Stack will throw an exception. The Peek() method always returns top most element in the Stack.What is top in stack?Stacks are a type of container adaptors with LIFO(Last In First Out) type of work, where a new element is added at one end called the top of the stack and an element is removed from the same end only. stack::top() top() function is used to reference the top(or the newest) element of the stack.
