How would you go about implementing a priority queue using a linked list in C? The typical linked list consists of head pointing to an element which points to another element(s), which eventually ends by NULL or the linked list's tail.

We are going to write a program to implement queue using linked list c++ programming language with proper output and explanation.

Example: (Linked List Head) ---->(Element Next) ---->(Element Next) ---->Null In the basic scenario, new elements are added to the list by using the First-In First-Out (add to the end of the list, remove from the front of the list) FIFO approach. In my case however, a priority value must be taken into consideration. More specifically, each element can be assigned priority of 1, 2 or 3. Elements with the highest priority are added towards the front of the list while those with lower priority are added towards the back. Insertions into the list maintain the FIFO order of each priority. Game Yu-0 Pegasus The Illusion Mod. So, if one is to enqueue the following elements one at a time: a 3, b 1, c 2, d 3, e 2 The output should be: a 3, d 3, c 2, e 2, b 1 (ordered by priority as well as the order of being added instead of the standard First-In First-Out approach which disregards the priority).

Here is what I have, but it DOES NOT feature priority. How would you go about implementing a priority queue? One way would be to use a sorting/priority algorithm. Besides the algorithm, some of the major unknowns/confusion for me is how and where the priority would be stored, would it be within the actual element such as: (Linked List Head) ---->(a 1 Next) ---->(b 2 Next) ---->Null or q_enqueue(&q, 'a', '1'); q_enqueue(&q, 'b', '2'); and how would I go about comparing the priorities while working with the pointers to create the sorting algorithm. You should consider implementing a double linked list. Basically this is like a simple linked list, but there is also a tail node that points to the end of the list, and every element in the list has a pointer forwards and backwards in the list. So high priority nodes get added to the front,and low priority nodes get added to the end.

Both these operations are very efficient with this data structure. I am not sure where priority 2 nodes get added:) The overhead above a normal linked list should be negligible.
