Stack operations

A stack is a linear data structure that follows certain order to perform the operation; the order will be LIFO (Last In First Out) data structure. In the stack data structure elements/items are removed and added only from the top. The topmost stack item/element is pointed by the top pointer and the element which is added to the stack first will get deleted at the last.
