WebA (bounded) queue can be easily implemented using an array using a five elements structure: structure stack: item : array. maxsize : integer. front : integer. rear : integer. size : integer. Since fixed-length arrays have limited capacity, we need to convert the array into a closed circle. If n is the array’s size, then computing indices ... WebIt also keeps track of the front and rear by implementing some extra logic so that it could trace the elements that are to be inserted and deleted. With this, the circular queue does not generate the overflow condition until the …

How to efficiently wrap the index of a fixed-size circular buffer

WebTo insert values in a circular queue, we have to check the following conditions. If FRONT = 0 and REAR = MAX - 1 , then the circular queue is full. If REAR != MAX - 1, then REAR can be increased. If FRONT != 0 and REAR = MAX - 1, then it means queue is not full. Algorithm to insert an element in a Circular queue WebCircular Queues Implementation using Arrays in C We can make our code circular by making minor adjustment and changes in the code. For example, our code can try to enter rear item the following ways – rear = (rear + 1)%size In this case if the queue is full, it will go to 0th position, if 0th position is empty.
