Answer:
an algorithm (pronounced AL-go-rith-um) is a procedure or formula for solving a problem, based on conducting a sequence of specified actions. A computer program can be viewed as an elaborate algorithm. In mathematics and computer science, an algorithm usually means a small procedure that solves a recurrent problem.
Multiple inheritance causes Diamond problem which happens when:
Class A is parent of class B and C
Now when class D will be inherited from both Class B and C it will have all the members of class A and B which if same will confuse the compiler to import which one?
C++ solves it by using virtual keyword with them and thus telling the compiler which one to inherit.
Java has introduced the interface concept rather then allowing multiple inheritance.
B) Advertising is the answer
Web design is awesome! Alright, so -
If you want to call some attention to text, you need to focus on the basic essentials.
You want your text to be brief and split up. If someone goes on your site and see's walls of text, they'll be overwhelmed and leave.
So, to call attention - make it brief, and split it up into nice paragraphs.
Another way to call attention to text is to have a <em>really </em>good colour scheme. Having text easy on the eyes attracts the reader more, and encourages them to dive deeper.
If your text is unattractive and hard to look at it, it'll certainly get their attention - but not the attention you want.
Finally, another way to call attention is with visual adjustments such as making text bold, making it <em>italicised, </em>making it ALL CAPS, <em>or just GOING CRAZY WITH UNNECESSARY TEXT ATTENTION ATTRACTING POWER!!!!!!!
</em>Ahem... Anyways, these are just a few ways to get their attention. =) If you need any other help, private message me because I love web development! =)<em>

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);
}
