C Program: Queue implementation using structure
7. Queue Implementation with Structures
Write a C program that implements a simple queue using a structure. The structure should contain an array representing the queue and front and rear indices. Include functions for enqueue and dequeue operations.
Sample Solution:
C Code:
Output:
Enqueued: 100 Enqueued: 200 Enqueued: 300 Dequeued: 100 Dequeued: 200 Enqueued: 400 Enqueued: 500 Dequeued: 300 Dequeued: 400
Explanation:
In the exercise above:
- The "Queue" structure is defined with an array '(arr)', 'front', and 'rear' indices.
- Functions like "initializeQueue()", "isEmpty()", and "isFull()" are used for queue management.
- The "enqueue()" function adds an element to the rear of the queue.
- The "dequeue()" function removes an element from the front of the queue.
- The "main()" function demonstrates the usage of the queue operations.
