Representation of Priority Queue in C
Priority queues can typically implemented using the data structures that can efficiently support the required operations – most commonly binary heaps. The binary heap is the complete binary tree where the each node is smaller than its children (min-heap) or larger than its children (max-heap). It can ensuring the retrieval of the node with the highest or the lowest value.
In C, priority queues can also be implemented using the various data structures and it can including the binary heaps, balanced trees or arrays. However, the binary heap can be the most common due to its efficiency. In C programming, the priority queue is implemented as the array where array elements represent the tree nodes.
typedef struct {
int items[MAX];
int size;
} PriorityQueue;
C Program to Implement Priority Queue
Priority queue is an abstract data type(ADT) in the computer science which is designed to the operate much like the regular queue except that each element has the certain priority. The priority can determines the order in which elements are dequeued – elements with the higher priority are removed from queue before those with lower priority. It can makes the priority queues an essential tool in the scenarios where the some tasks inherently take the precedence over others.
In this article, we will implement the priority queue using C program.
