This article tried to discuss the Difference between array, queue and stack. ![]() In stack, the process of insertion is called push operation and the process of deletion of the element from the stack is known as pop.Īnd, we can easily keep track of the last element using a pointer called top.ĭifference between Array, Stack and Queue Array In LIFO, the element which was inserted last will be the element which was removed first. If front -1 or front rear+1, which means that. If top-1, which means that the stack is empty. The enqueue operation performs the insertion of the elements in a queue while the dequeue operation performs the deletion of the elements from the queue. Stack data structure follows LIFO property i.e. It performs mainly two operations, enqueue and dequeue. Stack is a linear data structure in which a user can insert and delete an element from the same end which is known as a top. Peek(): This operation is used to get the value of the element from the front of the queue. IsFull(): This operation is used to check whether the queue is full or not. IsEmpty(): This operation is used to check whether the queue is empty or not. Basic Operations of Queue:Įnqueue: This operation is used to Insert an element at the end of the queue.ĭequeue: This operation is used to remove and return an element from the front of the queue. In other words we can say the element that goes in first is the element that comes out first.įor Example A ticket Queue outside a cinema hall where the person enters the queue first will get the ticket first. ![]() name of the array.Ī Queue is a linear data structure. Start ’Em, Sit ’Em Running Backs Fantasy Football Week 14: Don’t Lose Faith in Zack Moss. Queues are open from both ends: one end for inserting data ( enqueue ), and the other end for removing data ( dequeue ). Due to which we can easily calculate the position of each element by adding the memory location of the first element i.e. A Queue is also a linear structure that follows a First In First Out (FIFO) order, but they differ in how elements are removed. Queue is a container of objects (a linear. While inserting element in the stack we make the head pointer. Stack is a container of objects that are inserted and removed according to the last-in first-out (LIFO) principle. An Array is a collection of elements which are stored in a contiguous memory. The main difference in the dynamic implementation of stack vs queue are: In stack we define only one pointer 'head' pointing to the top element of the stack, where as in Queue we define two pointers 'front' and 'rear' pointing to the first and last element of the queue respectively.
