Queue is full throw Queue out of capacity error. * Enqueue/Insert an element to the queue. Printf("Invalid choice, please input number between (0-5).") isEmpty() function returns 1 if queue is emtpy

on success dequeue returns element removed Printf(" QUEUE ARRAY IMPLEMENTATION PROGRAM \n") * Run indefinitely until user manually terminates */ * Function declaration for various operations on queue */ Unsigned int rear = CAPACITY - 1 // Initally assumed that rear is at end You can use size to check empty queue i.e.

Check queue underflow and throw error if queue is empty, otherwise move to next step.

Step by step descriptive logic to dequeue element from queue. Elements from queue are always removed from front of queue. ĭequeue is the process of removing an element from queue.

Insert new element at the rear of queue i.e.

To do so we use rear = (rear + 1) % CAPACITY. Otherwise array index will go beyond its bounds. Now when you enqueue a new element to queue, rear must get updated to 0 instead of 100. Which means if suppose queue capacity is 100 and size is 10 and rear is at 99 which means front will be at 89. Note, that the increment should not cross array index bounds. You can use if (size >= CAPACITY) to verify queue overflow.

Verify queue overflow and throw error if queue overflow happens, otherwise move to next step.

Step by step descriptive logic to enqueue an element to queue. In queue elements are always inserted at rear of queue.

How to enqueue an element to queue?Įnqueue is the process of inserting an element to queue. Read more about unsigned int data type in C. Since these values will never go in negative. Note: I have declared these fields as unsigned. front keep track of index from where elements are removed.To facilitate first enqueue at zeroth index of array (see enqueue). Initially it is indexed to last element of queue. rear will keep track of the rear array index.size will keep track of the size of queue.Along with the queue definition we need few other variables to perform operations on queue. The above statement creates a queue, where CAPACITY is constant defining max capacity of the queue.

How to create queue data structure using array There are two basic operations that we generally perform on queue. I will explain the logic behind basic operations performed on queue. In this post I will explain queue implementation using array in C language. Such as queue of persons at ticket counter, where the first person entering queue gets ticket first. In real life you have come across various queue examples. Which means element inserted first to the queue will be removed first from the queue. Queue is a linear data structure where elements are ordered in special fashion i.e. While loop, Switch case, Array, Functions, Queue What is queue? And later we will learn to implement basic queue operations enqueue and dequeue. We will learn how to implement queue data structure using array in C language. In this post I will explain queue implementation using array in C programming. Write a C program to implement queue, enqueue and dequeue operations using array.
