In the dental industry, light-activated adhesives have been used for decades to help adhere braces to teeth as well as being used in other dental procedures. These adhesives are one-part translucent polymers that cure and harden when exposed to specific light spectrum. Many of these took up to 30 seconds to cure. New technology brings LED blue light curing which uses blue LED with UV light to cure and harden a light-activated adhesive in 3-5 seconds. Which result below would NOT be an advantage of this new technology?<u> A)There is a higher up-front expense.</u> B)Could be used in other areas such as sealing cracked pipes. C)No filters or cooling fan required due to quick curing and low heat emission. D)There is a major time savings when using the faster high–intensity curing lights.

Answer:
// Producer Thread
void *producer(void *param) {
buffer_item item;
while (true) {
item = rand() % 100;
sem_wait(&empty);
pthread_mutex_lock(&mutex);
if (insert_item(item))
printf("Can't insert item\n");
else
printf("Producer %d: produced %d\n", *((int*)param), item);
pthread_mutex_unlock(&mutex);
sem_post(&full);
}
}
// Consumer Thread
void *consumer(void *param) {
while (true) {
buffer_item item = NULL;
if (in > 0)
item = buffer[in - 1];
sem_wait(&full);
pthread_mutex_lock(&mutex);
if (remove_item(&item))
printf("Can't remove item\n");
else
printf("Consumer %d: consumed %d\n", *((int*)param), item);
pthread_mutex_unlock(&mutex);
sem_post(&empty);
}
}
Explanation:
An outline of the producer and consumer threads appears as shown above.
