wish helps you Let me give you an example :
See this image : Enqueue image (I can't post image here due to reputation points, So, giving the link)
code :
++q->tail;    // or q->tail=q->tail+1 or q->tail+=1;
if(q->tail==size)
    q->tail=q->tail-size;
q->data[q->tail]=item;

Hope that helps You could store the queue as a sorted linked list. Removing the front element is O(1) and inserting an element at the correct position is O(n).

I wish did fix the issue. while(intQueue.enqueue(i)) will continue to be executed as long as intQueue.enqueue(i)) returns a value that evaluates to true.
What you need to use is if.
code :
for(int i = 1; i <= 10; i++)
{
   if (i % 2 == 0)
   {
      if (intQueue.enqueue(i))
          cout << i << " has been added to the queue . . .\n";
      else
          cout << i << " has not been added to the queue . . .\n";
   }
}

I wish did fix the issue.
Do not cast malloc return value
code :
struct queue* tmp = malloc(sizeof(*tmp));
struct RCB* dequeue(struct queue* queue) {
        struct RCB *tmp1; 
        struct RCB *tmp2; 
        if(queue->front == NULL && queue->back == NULL) {
            printf("queue is empty\n"); 
        }   
        tmp1 = queue->front; 
        tmp2 = tmp1->next; 
        queue->front = tmp2; 
        if(queue->front == NULL) {
            queue->back = queue->front;
                printf("removed rcb from queue\n");  
        }
        return tmp1; 
}

wish of those help I was reading about queues in java implementation. I found the following code
code :
public String dequeue() {
    if (isEmpty()) {
        throw new RuntimeException("Queue underflow");
    } else if (first == last) {
        String f = first.item;
        first = null;
        last = null;
        return f;
    }

    String f = first.item;
    first = first.next;
    return f;

}
public void enqueue(String item) {
    Node x = new Node(item);
    if (first == null && last == null) {
        first = x;
        last = x;
        return; // return back when first node is enqueued
    }
    last.next = x;
    last = x;
}
