C Program to Implement Circular Queue | Queue Data Structure | L 56 | Data Structures & Application

Circular Queue Operations Basic Operations Of Circular Queue Insert – Adds element to the end of the queue Delete – Deletes an element at the front of the queue Peek – Check and returns the front element of the queue Circular Queue Insert Operation There are 3 conditions for Circular Queue Insertion If front = 0 and rear = MAX – 1, then the circular queue is full If rear != MAX – 1, then rear will be incremented and the value will be inserted If front != 0 and rear = MAX – 1, then it means that the queue is not full. So, set rear = 0 and insert the new element Circular Queue Delete Operation There are 3 conditions for Circular Queue Insertion If front = –1, Circular queue is empty. Print Underflow message If front = rear, then after deleting the element at the front the queue becomes empty. Set front = Rear = -1 If front = MAX–1, then after deleting the element at the front Set front = 0 Circular Queue Peek Operation If front = –1 and Rear = -1, Circular queue is empty. Print Underflow message Otherwise display the front element present in circular queue #circularqueue #circularqueueoperations #enqueue #dequeue #front #peek #queue #queuedatastructure #queueintroduction #datastructures #datastructure #datastructureplaylist #datastructuretutorials #cseguru #datastructureandalgorithm #datastructureandalgorithms #datastructureandalgorithm #datastructuresandalgorithms #datastructuredefinition #ds #dsa #datastructureintroduction CSEGuru Playlists #CSEGuru Compiler Design Videos: https://www.youtube.com/playlist?list=PLLykrwdi1zxExCT-6TBYkYhrRuWnnQFML CSEGuru DAA Videos https://www.youtube.com/playlist?list=PLLykrwdi1zxF22UVdcQnbiMfSOBTOiGVq CSEGuru Operating System Videos https://www.youtube.com/playlist?list=PLLykrwdi1zxENpYpQsaOSwquHGWXW0cfB CSEGuru Gate cse Videos https://www.youtube.com/playlist?list=PLLykrwdi1zxGlZpM7mHkKVh_Wytgw9lQ0 CSEGuru NET cse Videos https://www.youtube.com/playlist?list=PLLykrwdi1zxFJr5nT-xHMC4JWovtHSLuL CSEGuru Data Structure Videos https://www.youtube.com/playlist?list=PLLykrwdi1zxF0ezo6NCzrAW4nZ6zDl6k6 CSEGuru Sorting Algorithm Videos https://www.youtube.com/playlist?list=PLLykrwdi1zxFOkDhPnPeoPfRcXegcJ4bt
