Difference Between Stack and Queue In Data Structure

In this tutorial you will learn about the Difference Between Stack and Queue In Data Structure and its application with practical example.

Difference Between Stack and Queue In Data Structure

What Is Stack?

It is a kind of special linear data structure in which the item which is added in the last is removed from the very first and the item is to be added first is removed from the list in the last position; it works on the process of LIFO (last in first out). In stack there is only one end for insertion of date item and that is called top end, it is a kind of abstract data type where items and elements are stored in a limited size and it is mainly used in building of programming languages.

What Is Queue?

It is also a kind of linear data structure of non-primitive type in which the data item to added first will be removed first and that data item which is added in the last is to be removed last, in this kind of abstract data structure both the ends are in opened position so that the insertion and deletion of data items and elements are easier and in ordered manner. It works on the process of FIFO (First in first out). Queue is subdivided in types, they are, (1) Linear queue, (2) Circular queue, (3) Priority queue, (4) Dequeue.

Stack Vs Queue In Data Structure

STACK QUEUE
Stack follows LIFO (Last in first out) process. Queue follows FIFO (First in first out) process.
Insertion and deletion of data items and element occurs only from one(top) end. Insertion and deletion of data items and elements occurs from both the end.
Due to one open end only single pointer is used to denote stack. In Queue two pointers are used for back and front to denote queue.
The implementation process is very easy. In this the implementation process is complex as well as very tricky.
Operation like push and pop to be performed in stack Enqueue and Dequeue operations are performed under Queue
Stacks have nothing to perform. Queue have other variants for performance like Circular, priority, Linear etc.
