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);
}
Answer:
Option A is the correct choice answer for the above question.
Explanation:
In an MS-Powerpoint document, when a user wants to copy the selected shape and drag that shape for use in slides then he needs to--
- Select the shape
- Press the Ctrl key and
- drag that shape on the slide of the powerpoint.
Then the user gets the shape on the slide for their personal use.
The question scenario also suggests the same which is described above. hence Option A is the correct answer while the other is not because--
- Option B suggests 'ESC' which is used to escape any running program.
- Option C suggests about ALT key which is of no use for the MS-Powerpoint document.
- Option D suggests about TAB key which is used to make the space between two texts or diagram.
