typedef struct queue {

  int q[max];
  int qhead;
  int qrear;

} queue;


void init_queue(queue *QUEUE)
{
  QUEUE.qhead = 0;
  QUEUE.qrear = -1;
}
void enqueue(queue *QUEUE,int data)
{
  QUEUE.qrear++;
  QUEUE.q[QUEUE.qrear] = data;
}

int process_queue(queue *QUEUE)
{
  if(QUEUE.qhead > QUEUE.qrear) 
    return -1;
  else
    return QUEUE.q[QUEUE.qhead++];
}

I am implementing queues using arrays just to keep it simple. Wats the error with the above code?

I read about unions the other day( today ) and tried the sample functions that came with them. Easy enough, but the result was clear and utter garbage. The first example is: union Test { int Int; struct { char byte1; char byte2; char byte3; char byte4; … >>> More
