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);
}
Answer:
The answers are explained below
Explanation:
1) Identify the potential classes in this problem domain be list all the nouns
class Customer
class Acco unt
2) Refine the list to include only the necessary class names for this problem
the class customer is not necessary to solve the problem itself, therefore the only class could be the account class
3) Identify the responsibilities of the class or classes.
The responsibilities of the class account will be
* determination of the type of account--> Acc ount . type(char)
* deposit money into the account --> Acc ount . de posit(float)
* withdraw money into the account --> Acc ount . with draw(float)
* show balance of the account --> Acc ount . bal ance()
* generate interest --> Acc ount . int erest()
Please join the words together. I used spaces due to regulations
