Queue Using Linked List in C++
The queue can implemented using the linked list which consists of the nodes where the each node contains the two parts:
- Data: The value or the data can be stored in the node.
- Next: The pointer to the next node in queue.
The queue itself maintains the two pointers:
- Front: It can be used the points to the first node of the linked list.
- Rear: It can be used the points to the last node of the linked list.
When the queues is empty, both the front and rear pointers are the nullptr. When the new element is enqueued, it is added at the rear and when the element is dequeued, it is removed from the front.
C++ Program to Implement Queue using Linked List
Queue is the fundamental data structure that follows the First In, First Out (FIFO) principle where the elements are added at the one end, called the rear and removed from other end called the front. In this article, we will learn how to implement queue in C++ using a linked list.
