If the stack is not empty, then print the element at the top and decrement the top.īelow we have a simple C++ program implementing stack data structure while following the object oriented programming concepts.If the stack is empty, then print error of underflow and exit the program.If the stack is not full, then increment the top and add the element.If the stack is full, then print error of overflow and exit the program.Here we will implement Stack using array. Arrays are quick, but are limited in size and Linked List requires overhead to allocate, link, unlink, and deallocate, but is not limited in size. Let stack to be implemented be ‘s’ and queues used to implement be ‘q1’ and ‘q2’. Stack can be easily implemented using an Array or a Linked List. A stack can be implemented using two queues. Expression Conversion(Infix to Postfix, Postfix to Prefix etc).Linked list allocates the memory dynamically. The order is First In First Out (FIFO).A good example of a queue is. You push a given word to stack - letter by letter - and then pop letters from the stack. Instead of using array, we can also use linked list to implement stack. Like Stack, Queue is a linear structure that follows a particular order in which the operations are performed. The simplest application of a stack is to reverse a word. As with lists and arrays, Python conflates the difference between stacks.

Stack is an abstract data type with a bounded(predefined) capacity.
