One namespace contains multiple queues and topics. Service bus namespace is a container for all messaging components. Now let's see the step by step implementation of the below to design a solution: Another benefit is load leveling, which means sender sends messages at a different rate and the receiver can process messages at a different rate, as both are independent in sending and processing. The benefit of using queue is, it creates decoupling between sender and receiver, means sender and receiver should not be available at the same time while sending the message as messages are stored in a queue. Implementation of dequeue() in C programming language РІв‚¬вЂ™Р”Р‡or a complete Queue program in C programming language, please click here.The sender sends the message, adds it into the queue and the receiver processes the message in a FIFO (First In First Out) manner. Step 4 РІв‚¬вЂ™ Increment front pointer to point to the next available data element. Step 3 РІв‚¬вЂ™ If the queue is not empty, access the data where front is pointing.

Step 2 РІв‚¬вЂ™ If the queue is empty, produce underflow error and exit. The following steps are taken to perform dequeue operation РІв‚¬вЂ™ Implementation of enqueue() in C programming language РІв‚¬вЂ™Р”Р„ccessing data from the queue is a process of two tasks РІв‚¬вЂ™ access the data where front is pointing and remove the data after access. Sometimes, we also check to see if a queue is initialized or not, to handle any unforeseen situations. Step 4 РІв‚¬вЂ™ Add data element to the queue location, where the rear is pointing. Step 3 РІв‚¬вЂ™ If the queue is not full, increment rear pointer to point the next empty space. Step 2 РІв‚¬вЂ™ If the queue is full, produce overflow error and exit. The following steps should be taken to enqueue (insert) data into a queue РІв‚¬вЂ™ Therefore, its operations are comparatively difficult to implement than that of stacks. Queues maintain two data pointers, front and rear. If the value of front is less than MIN or 0, it tells that the queue is not yet initialized, hence empty. If front is less than MIN OR front is greater than rear Implementation of isfull() function in C programming language РІв‚¬вЂ™

In case we maintain the queue in a circular linked-list, the algorithm will differ. Implementation of peek() function in C programming language РІв‚¬вЂ™Р”Р„s we are using single dimension array to implement queue, we just check for the rear pointer to reach at MAXSIZE to determine that the queue is full. The algorithm of peek() function is as follows РІв‚¬вЂ™ This function helps to see the data at the front of the queue. Let's first learn about supportive functions of a queue РІв‚¬вЂ™ peek() In queue, we always dequeue (or access) data, pointed by front pointer and while enqueing (or storing) data in the queue we take help of rear pointer. Isempty() РІв‚¬вЂ™ Checks if the queue is empty. Peek() РІв‚¬вЂ™ Gets the element at the front of the queue without removing it. Here we shall try to understand the basic operations associated with queues РІв‚¬вЂ™Р”В®nqueue() РІв‚¬вЂ™ add (store) an item to the queue.Р”Вequeue() РІв‚¬вЂ™ remove (access) an item from the queue.Р”Р‡ew more functions are required to make the above-mentioned queue operation efficient. Queue operations may involve initializing or defining the queue, utilizing it, and then completely erasing it from the memory. For the sake of simplicity, we shall implement queues using one-dimensional array. The following diagram given below tries to explain queue representation as data structure РІв‚¬вЂ™Р”Р„s in stacks, a queue can also be implemented using Arrays, Linked-lists, Pointers and Structures. Queue RepresentationР”Р„s we now understand that in queue, we access both ends for different reasons.

More real-world examples can be seen as queues at the ticket windows and bus-stops. Queue follows First-In-First-Out methodology, i.e., the data item stored first will be accessed first.Р”Р„ real-world example of queue can be a single-lane one-way road, where the vehicle enters first, exits first. One end is always used to insert data (enqueue) and the other is used to remove data (dequeue). Unlike stacks, a queue is open at both its ends. Queue is an abstract data structure, somewhat similar to Stacks.
