Moving on with this article on Queue In C, Limitations Of This ImplementationĬonsider a queue, with size 5. A Queue has a complexity of O(1) as no loops are present in any operation. Check if the queue is empty here as well. Just display the queue like how an array. Otherwise, print the first element, that is the element that will be deleted and increment front. In the delete part, check again if the queue is empty. Moving on with this article on Queue In C, The rear is then incremented by one and the at the location rear add the new item. Check if the queue is full, if yes give the overflow message or else check if the queue is empty.
