Answer:
import java.util.Arrays;
import java.util.Scanner;
public class num1 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter length of the array:");
int len = in.nextInt();
double [] temps = new double[len];
double avgTem;
int k =0;
double total = 0;
for( k=0; k<temps.length; k++){
System.out.println("Enter values for the array");
temps[k]=in.nextDouble();
}
System.out.println("The Arrays contains the following values");
System.out.println(Arrays.toString(temps));
// Computing the average of the values
for(k=0; k<temps.length; k++){
total = total+temps[k];
}
avgTem = total/(temps.length);
System.out.println("The average Temperature is: "+avgTem);
}
}
Explanation:
- Using Java programming language
- Import the Scanner class to receive user input
- Prompt User for the length of the Array, receive and store in a variable len;
- Declare a new double array of size len double [] temps = new double[len];
- Using a for loop, continually prompt user to enter values into the array
- Display the values of the array using Java's Arrays.toString method
- Use another for loop to add up all the elements in the arraay and store in the variable called total
- Outside the second for loop calculate the average avgTem = total/(temps.length);
- Display the average temp.
Answer: Switch
Explanation: ARP spoofing is a illegal harmful activity in a disguised manner by a person who tries to send the ARP (Address resolution protocol)request.The disguised ARP request is sent to steal the confidential data by the overloading of the switch because of the numerous amount of the ARP request. This attack is done in the local area network .Therefore, the correct option is switch.
