Data structures using C,Write a C Program to implement Priority Queue using structure.Priority QUEUE is a abstract data type in which the objects are inserted with respect to certain priority. In this program, we created the simple ascending order priority queue using the structure, here items are inserted in ascending order. Structure is a c …
A priority queue is a data structure where each element is served according to its priority rather than just the order it arrived. A multiple priority queue implements this with several separate queues — one per priority level — so that higher-priority items are always removed before lower-priority ones. This C program builds a simple …
A queue implemented with a linked list in C has no fixed size limit — it grows and shrinks dynamically using malloc and free. Each node holds a value and a pointer to the next node. Two pointers, front and rear, track the dequeue end and enqueue end respectively. Linked List Queue vs Array Queue …
A circular queue in C solves the main limitation of a linear queue: wasted array slots after dequeuing. In a linear queue, rear keeps advancing rightward; once it hits the end of the array, the queue reports “full” even if dequeued slots at the front are free. A circular queue wraps rear back to index …
A queue program in C implements the FIFO (First In, First Out) data structure — elements are inserted at the rear and removed from the front, just like a real queue. The two core operations are ENQUEUE (insert) and DEQUEUE (remove). This page covers the array-based linear queue with all operations, a step-by-step trace, and …
