Your implementation may not be the most efficient way of using an array to implement a queue, but given that you've decided to implement it this way, your enqueue method is a bit more complex than it need be.You have a field sz that can be used to determine where the new entry has to be put rather than checking through to find the first non-null. And the search for a non-null won't work properly anyway as the dequeue isn't clearing the last element moved forward.The sz field will also tell you when you need to resize, rather than detecting that need by an exception.
The major problem with the queue implemented using an array is, It will work for an only fixed number of data values. That means, the amount of data must be specified at the beginning itself. Queue using an array is not suitable when we don't know the size of data which we are going to use. A queue data structure can be implemented using a linked list data structure. The queue which is implemented using a linked list can work for an unlimited number of values. That means, queue using linked list can work for the variable size of data (No need to fix the size at the beginning of the implementation). The Queue implemented using linked list can organize as many data values as we want.In linked list implementation of a queue, the last inserted node is always pointed by ' rear' and the first node is always pointed by ' front'.

ExampleIn above example, the last inserted node is 50 and it is pointed by ' rear' and the first inserted node is 10 and it is pointed by ' front'. The order of elements inserted is 10, 15, 22 and 50. OperationsTo implement queue using linked list, we need to set the following things before implementing actual operations. Step 1 - Include all the header files which are used in the program.

To solve this problem by joining the front and rear ends of a queue to make the queue as a circular queue Circular queue is a linear data structure. It follows FIFO principle. In circular queue the last node is connected back to the first node to make a circle. Circular linked list fallow the First In First Out principle. Elements are added at the rear end and the elements are deleted at front end of the queue. Both the front and the rear pointers points to the beginning of the array.
