Reflection is the return of light to the medium it came from when it encounters a mirror.

Assume your sketch has a variable named silo, which stores an object that is defined by a class you have created. The name of th
yulyashka [42]

Answer:

c. let v = silo.volume();

Explanation:

When you create and initialize a new object you pass through that object's class constructor. The constructor is in charge of initializing all the necessary variables for that class including radius and height. Once you save the object in a specific variable (silo) you need to call the class methods through that variable, using the '.' command. Therefore, in this scenario, in order to call the volume() method you would need to call it from the silo object and save it to the v variable, using the following statement.

let v = silo.volume();

The Sleeping-Barber Problem:
s2008m [1.1K]

Answer:

Explanation:

Following are the Semaphores:

Customers: Counts waiting customers;

Barbers: Number of idle barbers (0 or 1)

mutex: Used for mutual exclusion.

Cutting: Ensures that the barber won’t cut another customer’s hair before the previous customer leaves

Shared data variable:

count_cust: Counts waiting customers. ------------copy of customers. As value of semaphores can’t access directly.

// shared data

semaphore customers = 0; semaphore barbers = 0; semaphore cutting = 0; semaphore mutex = 1;

int count_cust= 0;

void barber() {

while(true) { //shop is always open

wait(customers); //sleep when there are no waiting customers

wait(mutex); //mutex for accessing customers1

count_cust= count_cust-1; //customer left

signal(barbers);

signal(mutex);

cut_hair();

}

}

void customer() {

wait(mutex); //mutex for accessing count_cust

if (count_cust< n) {

count_cust= count_cust+1; //new customer

signal(customers); signal(mutex);

wait(barbers); //wait for available barbers get_haircut();

}

else { //do nothing (leave) when all chairs are used. signal(mutex);

}

}

cut_hair(){ waiting(cutting);

}

get_haircut(){

get hair cut for some time; signal(cutting);

}
