Answer:
scores.append(6,2)
Explanation:
This is a complicated question because in theory, scores.insert can also add values, but I am sure that the only line of code that would work is scores.append(6,2)
The threats as well as the risk and vulnerabilities are present with the WLAN. The WLAN would encounter security issues with the range of the signal which is wireless, SSID broadcasting, password security and the packet sniffing or the capturing of signal.
Answer:
import java.util.Scanner;
public class num6{
static int getTestScores(){
System.out.println("Enter the Score");
Scanner in = new Scanner(System.in);
int score = in.nextInt();
return score;
}
static double calcAverage(int score1, int score2, int score3){
return (score1+score2+score3)/3;
}
static void displayAverage(double ave){
System.out.println("The Average is "+ave);
}
public static void main(String[] args) {
int num1 = getTestScores();
int num2 = getTestScores();
int num3 = getTestScores();
//Calling Calculate Average
double average = calcAverage(num1,num2,num3);
//Calling displayAverage
displayAverage(average);
}
}
Explanation:
- Using Java programming Language
- Create the four methods
- getTestScores() Uses the Scanner Class to receive an in variable and return it
- calcAverage() accepts three ints as parameter calculates their average and return it
- displayAverage() Accepts a double and prints it out with a concatenated string as message
- In the Main Method, getTestScores is called three times to obtain three numbers from the user
- calAverage is called and handed the three numbers
- printAverage is called to output the calculated average
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);
}
The Intel socket that Intel recommends you use a liquid-cooling system on is the LGA2011.
