Answer:
float(distance) / speed
Explanation:
Given the variable <em>distance</em> and <em>speed</em> in a program that hold a integer value respectively. We can perform the division between the two variable using / operator. Since both distance and speed are integers, we need to convert one of them to float type to perform the floating point arithmetic. Otherwise the division output will be rounded up to the nearest integer which is not a desired result.
I think if a large number are accessing at the same time you would have to wait for many to clear up
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.
